When I was young I had a lust for the SA-9800 and TX-9800.

A friend of mine gave me one of these as a Christmas gift because he knows I enjoy messing around with vintage equipment,needs 4 knobs that are missing but other than that it works and just needs cleaning

I had tons of issues with the zero switching bias circuit in my SX-1980 when i first got it. I also have a SA-9800 in my rack with my SX-1980 . I love both of these pieces of equipment

Nice looking amplifier Tony thanks for posting the restoration!

Really like the way you improvise when you run into something unexpected, or out of the ordinary.

Assuming my SA-9100 has that same slight bass elevation, it probably explains why I like listening to it so much. It's very subtle - there's no lack of detail on the top end, just a slightly greater presence in the lower mid-range than my cooler, thinner-sounding Emotiva gear. In my opinion, these old Pioneer amps work wonderfully with horn-loaded Klipsch speakers. Great video! Thanks.

I had one of those amps, its now with my son. It has a very clean and clear sound and can drive a set of HPM-100's like there is no tomorrow

Thank you for the great video of this classic amp. I very much enjoyed the video and your explanation of what you were doing and why you did it. Vintage electronics restoration is a dying art form as most technicians are either retired or have passed on. I am nowhere near your level but I do restore vintage electronics all because in my opinion, the older gear was made in the days when the sound quality was more important than colored flashing LED lights that tend to be used on the new junk being sold today.

IMO the SA-7800, SA-8800 and SA-9800 are the most beautiful amps ever built

Hello sir. If you still have these and you would be willing, I need one of the smaller knobs for my restoration. I have an SA-9800, and that's the only cosmetic part I still need. Pretty please with sugar on top? I would pay you a decent price.

Very nice amp. New amps won't do better. If anything they will cost more and and do worse. The twin transformers is a nice touch. Reminds me of the Harman Kardons with the Dual or Twin supplies. Nothing like a nice healthy linear power supply. Nice work there Tony.

Just got hold of one that's sold with faults. Cosmetically very good, but hopefully I'll be able to find someone local who can service/repair this unit. It's a beautiful unit and definitely worth gettting this back to working condition.

I enjoy listening to somebody that knows what they are talking about telling me how good my amp is.

You are very talented Tony. Love my sa-9800 just would love to have it restored by u . Lol

Great video, and points for explaining these non-switching amps. My 'daily driver' is a restored SA-9800 and it never ceases to impress. Not sure if it was a brain fart but the SX-1980 isn't one of them - it's a 'fast' amp with ring-emitter outputs but not a non-switching topology, just conventional A/B. The last thing we need is another reason for their eBay prices to rise LOL

Just bought a 9800 today. Yes, the prices are already high!

I always liked the front panel design of Pioneer, Kenwood and Sony Equipment (from the 70's and early 80's). The only piece of gear from that era that I still own is a Sony TA-2000f Pre-amp, which I re-built. It has been my only pre-amp since 1975. I only use the line&tone amp section on it today. The phono section can't really compete with the low-noise IC based phono preamps that you can buy today.

lol, I don't even own a TV but have 4 vintage hi-fi systems set up throughout the house with many more components shelved. Anyway, just wanted to thank you for making these videos. You help many of us with your knowledge.

Really valuable video series and I am really appreciate your effort on this youtube videos. I am looking into each and every videos and learning many new things..!!!

on 35:00 I usually just remove this type of switch, disassemble completely, use diamond brush to clean and polish all conductors and afterwards clean w contact cleaner w silicon lubricant and assemble back. This way I am 100% positive on it, I also do the same thing w other tumbler switches. Now I am looking for one unit for myself, want to do modification to add CD and MD inputs (instead MM/MC), do new silkscreen on front panel and this MC/MM switch put on the back of the amp.

Hi Tony, first of all thank you for your excellent videos, a real joy to watch. I have a SA 9800 which plays and sounds fine with one exception that drives me a bit crazy because I can't get it together in my head. When I'm in the MC channel all sounds fine when I do not touch the tone (bass) control. The signal first crackles and then vanishes completely when I 1, switch off tone control or 2, turn up the bass (one step is enough) or 3, activate loudness. When I switch back the signal is back after about a second. All that only happens in the MC mode. The unit is not restored yet, I want to do a complete revision, but maybe you might have an idea where to look for this problem first. Thank you a lot in advance, Martin

These NSA amps can be tricky. They use high speed transistors and replacements *must* be high speed also. Especially the drivers and outputs.

Another awesome fix. Positive feedback: I would really like to have seen more of the actual fixing in the video, even if it had to be a 5 part series, unedited. Thank you for sharing your skills. 👍👍👍👍👍

Beautiful work. I want one

Great Video and as always extremely interesting. The really Classic Consumer Electronics manufactured before 1980 were designed and built to be serviceable. The introduction of microprocessors, surface mount technology, Digital Signal Processing, Digital Sampling, etc. etc. etc. has made it much more difficult for user service friendly Consumer Products. One tiny component does the tasks of hundreds (and sometimes even thousands) if discrete components and circuits. Those propriatorey devices are usually a) difficult to obtain, if not impossible, b) exclusive only to a few select Factory Repair Outlets, or c) extremely expensive and cost prohibitive to most owners. The classic Pioneer, Marantz, Sony, etc devices before 1980 were well designed, fairly easy to be serviced by most repair techs and of a quality that allowed for a very long useful life. It seems the new modern digital marketplace has created disposable devices with planned obsolescence. So, Tony, watching your repair processes are such a treat. My personal understanding of the entire process for your projects is most enjoyable and very appreciated that you stop to give pause to explain why you do what you do. Can’t wait for the next part!

It appears most vintage gear even hi-end units the speaker terminals were very cheaply made spring-loaded junk, that would be one concern to replace that with nice binding posts.

Another amazing video! , I always wanted to ask you , what do you think about the recap kits that are sold in ebay? , Can a person with some little knowledge on electronics be able to recap and amp with those kits without doing a mess?, I have a Yamaha ca-1000 III (Ca-2000 in the US) I want do to the recap by myself cuz there are no people in my country which can do the job.

Excellent video. I want to make you a query. My SA-9800 has the same fault in which the display lights up with very low brightness. I understand that it is a problem with the capacitors on the Fluorscan board, or it is also a problem in the power source. Thank you for your comments.

First of all, thank you for the beautiful video. Like. In second order, would you please say me in wich video you teach how build a transistor couple with a matched pair and put it together in epoxy? Thanks.

Great video. I am the proud owner of one these that I bought new way back in the day. I will be restoring it as well, and probably selling it after that. But, I am in need of one thing...one of the smaller knobs. I noticed that the speaker selector knob on yours was not an exact replacement...I don't suppose you have an extra small know or know of a source?

the flipped upside down power supply board where its discolored from the 2 transistors mounted on small alum heat sinks, cant you remount them with extended wires above the board in a new proper higher location, or leave them there and ruin all the new stuff you just swapped out with same heat stress after a few years of use , also a list of all offending transistors to get replaced with new cross ref ones would be great !!

Great work on that Pioneer SA 9800 Tony. As usual you do a might fine job. I have a question for you.... I have my Stand alone Blast King Powered Sub-woofer box and the Clipping light keeps coming on, even at low volume. I change all the electrolytic capacitors whit high quality ones and no change, it still clip at low volume. I attach the scope to the speaker out to test and it indeed clips. Can you tell me what I can check for this problem? Thanks and have a great day.

Great video. I have a question for you which I have not been able to find an answer. All of the Pioneer SX series receivers have 2 prong non polarized and non grounded 2 prong power cords. Is this safe? Is it advisable to convert these old power cables to newer, safer 3 prong polarized and grounded plugs? If so, have you done such a conversion in one your past videos? If you have not done such a conversion and you think it’s advisable to do so, would you consider doing a short video on this subject? I have the Pioneer SX 1010 which I love. Thank you for any info you can shed on this subject.

Hi, just got this amp but the Florescent Display isn't working and also there is a loud buzzing sound from the speakers when connected to both A and/or B Terminals... Please advise. Thank you

is it acceptable to use the nichicon fine gold capacitors to replace the lower quality capacitors if you have a boat load to use up... ie power supplies and other circuits? thank you...

Nice job Tony! I am currently rebuilding my SA 9800 and i have few question for you . What replacements did you use for transistors on AWH channel board and Power board .Can you write me what for what? Was the display only dirty or did you change anything with the current? Greeting from Poland Rafael

I have one on my bench right now.

If you don't have right value of potentiometer, put next bigger value because you adjusting a current and always can reduce it to right value. Jumper for connection protection and power circuit was used for bay pass protection function and force to switch relay directly from power supply board when amplifier is on.

great movie, what did you do to make the display shine so bright?

Mark, over at Blueglow electronics even made one of my stinger cables on one of his videos and goes into detail as to how he made his. Thanks for the comment!

Good job! These late 70's and early 80's high end Japanese were generally well built, and still sound good some 40 years later. However, some are not so easy to maintain. This Pioneer is really dense, so I guess the wiring and so on was a time consuming job, specially to access both sides of boards. Your idea of getting a slope to your Multiturn pots is great! However, most manufacturers produce their pots with relatively short legs (compared to transistors). I also appreciate the wood cabinets or flanks, and I suppose you will later replace your whole Pioneer ensemble using good looking real wood. Many Sansui, Akai, Sony also shared these fragile panel. Never an easy job to replace if you don't have proper tools to get the flanges and profiles required. Last, if you want a perfect finish, you can varnish or lacquer these, but it's also a time consuming job. Best I've ever seen is some Piano lacker for JBL speakers!

Hi Thank you so much for the great video. I have a few questions. 1. Do you have a link to where you set the bias? 2.

Hi Tony, great job on that Pioneer, it very handsome and great sounding amp. Hi have love my SA8800 but I have no use for it anymore. I have had it for 42 years and I am selling on ebay if anyone wants to get one very similar.

Pioneer means : DISCHARGE THE BIG CAPS ! They hold their power for MONTHS !

Hello friend, is this for sale?

I wouldn't say Pioneer were not making quality amplifiers in the 1980's. I have owned a lot of their amplifiers and worked on them from the 1980's. Like the A88X from the Elite series dual mono and twin PSU's and the A70 which I am going to restore. They are of all metal construction all nobs and front panel's are made of aluminum. I have owned the Pioneer SA7800 which is from the same series as the 9800 and it was no great shakes sound quality wise. If you ever get the chance of a Pioneer A90 manufactured between 1983 - 1985 snatch it that's if you can find one!!! In my opinion this was the best integrated amplifier Pioneer ever made and the most powerful at 200 watts RMS per channel twin mono and massive dual torroidal transformers. Pioneer went down hill in the 1990's that's when the plastic seem to take over.

I have no idea of the importance of this observation, but at 38:30 or just after, you had a loose component on what I think is the low level phono amp board. It looked like an axial electrolytic cap stood on its end. If the end of the board farthest from the camera is the top, it was near the top and on the right. I expect you fixed it just like you fixed the loose ganged volume pot off camera. BTW, was that loose bots and nuts or a loose set of solder joints?

@xraytonyb

Those tall silver caps are actually polystyrene capacitors. They are very high quality caps used in applications such as phono stages. They are somewhat large for their value and can be somewhat expensive, which is why you don't see them more often. As for the volume pot, it was just a loose mounting nut.

What were those dual transistors? I've been building things with duel JFETs and other dual transistors lately.
