You are the finest instructor on KZread and I only wish I could apprentice with someone as patient and experienced as you. I am learnin'.I want to understand as much as necessary before I tackle a project-an old Hitachi receiver is in need of some upgrade- I am trying to learn all the basic components-and how they interact in the circuits to produce sound. Fascinating! Your awareness of we novices is comforting.

I'm glad that the video helped you out. Thank you very much for watching.

I just picked up an AU-11000 and this video helped tremendously. Thanks! Heading to part 2 now.

Glad it helped! Man, you got a great piece of gear! Enjoy your AU-11000!

Nice to see a receiver with connectors on each board. Not like the Marantz with all connections done with wire wrapping. Same with the Tandberg TR2060 I just finished restoring, 6 boards inside and all connected with plugs so I could disconnect one board at a time. Work on it and put it back in and test after each board was done. Yes, I did take lots of pictures... When removing the bigger capacitors with thicker pins, I just cut the pins flush with the board on the copper side, easier to remove that way. Their going in the trash anyway. That's a big receiver BTW. Funny how they decided to go with some knobs black, and the rest in brushed aluminum. Maybe I could do that on my Optonica 1515 that's missing one black knob...

Thanks for your comments. The main point I wanted to get across was with glue, soldered pins from the old capacitors bent at 90 degree angles and tight spaces there are many issues to consider to remove them safely. I was showing what you will run into. Thanks again!

Got one today. Going to school! Thanks

Your videos are really great. Upon seeing several of them, you have encouraged me to do something I bear in mind form a while. I used for decades a Sansui A40 in my stereo setup. I have made over the years a couple of repairs, replacing electrolytic capacitors form the power section, rectifier bridge, power transistors and also modifying the heatsink design, installing a bigger one, including a separation from the motherboard, avoiding it to transmit high temperatures to the board while working with high power levels. Later on I bought a Pure Acoustics Junior F tower speakers and later on a 3 way Sony speakers. By the way for many years I used it with DIY speakers. Well, while playing music with the 4 new speakers, enjoying Carlos Santana and Andrea Bocelli, it started to make a strange noise at the left channel. ...So I decided to change for anew one. I was completely out of date about audio gears, so a second hand Denon AVR 1611 took my attention and I thought it would be wonderful. But it was only for movies, Blueray, BUT not for CDs. I noted that music from CDs was lack of bass punch as the Sansui used to be. Then the music experience clearly showed that something was missed in the way of feeling it. To make the story short, this week I set up again the Sansui and music has come to life again!!! The Sansui is a silver plate unit and is in very good condition. In fact if you see it you will tell that it is brand new. Nevertheless I will do some potentiometers and selector switches cleaning and put it again in service. Thank you again for your grant videos

Your welcome and thank you very much for your kind words. Thank you also for sharing your story. Your A-40 is a fine unit and I'm glad that you got her going again. It's so nice to hear that my video's in some way encouraged you to turn back the clock and get your Sansui playing music again. Thank You once again!

Vintage Audio Addict , in fact it has just come to life again. I have cleaned up all selector switches and potentiometers and had to repair the power switch that gets broken while cleaning LOL (that thing happens!!!). My next step is changing some internal components, like trim pots that allows to adjust bias . My idea is to change with multi turn trim pots in order to get a more precise adjustment. Now the offset voltage is about 15 mV. Is that fine or should be less?

Awesome content - love this stuff!

Good work on the vids, glad I found this channel! I had a couple of ideas to share just because I enjoy the way the channel is shaping up, kinda long -- feel free to disregard or until you have the time!: I dig the content as it is and only wanted to share this if you're ever looking for a vid idea in the future. None of the vintage audio channels have any content involving a basic thing most novices are mystified by: reading a vintage 70s/80s solid state schematic and working through it. Maybe it'd be a popular video if someone went through a schematic starting at one area and giving general pointers on navigating through & verifying voltages along the way with a meter? Not an entire tour through every bit of the schematic but maybe one from AC cord thru the power supply and/or from the rca inputs (aux or phono etc) through to the speaker outputs. Maybe no one has made a vid on this topic because of something im unaware of such as it being too time consuming/too much editing? Lastly, maybe you already have a lazy susan or prefer not to use one but I wanted to share something that may make filming easier: homedepot (prob available elsewhere too) stocks a compact 6" square rotating bracket that has a 400lb load capacity and is only $6. Add two pieces of wood and top it with glued on rubber or a yoga mat and you got a killer light weight 360deg rotating lazy susan to help ya wrestle those amps into the perfect camera position. link to the item: www.homedepot.com/p/Everbilt-6-in-Square-Lazy-Susan-Turntable-with-400-lb-Load-Rating-49548/203661089?g_store=6336&mtc=Shopping-B-F_D25H-G-D25H-25_4_BUILDERS_HARDWARE-Multi-NA-Feed-LIA-NA-NA-BuildersHardware_LIA&cm_mmc=Shopping-B-F_D25H-G-D25H-25_4_BUILDERS_HARDWARE-Multi-NA-Feed-LIA-NA-NA-BuildersHardware_LIA-71700000044822926-58700004636006010-92700039037730264&gclid=Cj0KCQiAxfzvBRCZARIsAGA7YMyqC222kk2CwqGWPw_Bp0PkLtBO5tW6f3jWfnoc06_yB6gKTLs_r7EaAkhSEALw_wcB&gclsrc=aw.ds

No, I didn't. I like to avoid glue if I can. I'll just not sure how any particular glue would react with the old assemblies. I soldered them in so there is not to much movement.

Sir do you sell or could you tell me where can buy vintage audio.

Hi. First: Thank you so much for the videos. They are very useful. I am also currently restoring an AU-9900. I have a question: If I am not mistaken, you did not look at the big power supply capacitors. Is there a reason for that? In my case, they don't seem to be ok. I am measuring too high ESR values. That brings me to my second question: It seems impossible to find the right replacements. What would you recommend? Greetings from Belgium.

Your welcome and greeting from the USA. I'm a hobbyist but I have most all the parts I need in stock to repair or restore a piece of vintage audio equipment except for the filter capacitors. I had to order the filter capacitors and I didn't get them installed until after I completed the video. Yes, you can still get the filter capacitors. In the USA, mouser.com or digikey.com will usually have what you need. In Belgium you probably have your native electronic part suppliers. I can't remember the filter capacitor dimensions but you just need to measure their circumference and height. Then find a suitable replacement.

@@vintageaudioaddict Thanks for your answer. Were your filter caps also with screw terminals? This (combined with their dimensions) makes them very hard to find.

Is it okay to use bipolar caps for standart caps? Im about to recap my ca 610 and im kind of a newbe. I recognized you used the grenn Muse cap wich is bipolar for a standart one.

@vintageaudioaddict

4 жыл бұрын

Thanks for your question. I used a bipolar cap to replace a bipolar cap. I'm not sure what you mean by "standard caps" but if you replace a electrolytic capacitor using a electrolytic capacitor you can't go wrong. A bi-polar the same way, Sometimes a film capacitor can have benefits as a replacement for a electrolytic capacitor in the signal path. It's great that you are asking questions before you start your project. It's not that hard to recap most units like your Yamaha but like everything in life experience is very important. Take your time, don't be in a rush. Good Luck!

Hi, I don't know what the issue could be. This equipment being 40-45 years old it could be almost anything in the preamp/tone section.

How do you know (Phono Board example) where and why changing electrolitics for film? You changed electrolitics (on the bottom side of the PCB) for two film caps. Can you explain this please? I am total newbie in hands-on. I know a bit of theory but treat me as an idiot. Thanks a lot for your informative videos! ;-)
