The way you interpret systems and subsystems, circuits and components (with or without documentation) and then modify manufacturers testing procedures etc. to maximize functionality is so amazing to me. Thanks for the fun Tony 🎉😃

“Looks like a candle threw-up in there” 😄

Bad switches, and difficult pots,wax, I really will let someone who knows what they are doing. Definitely not me. Tony you're the man for the job.

This is the most beautiful radio I have ever seen

Hey 👋 Tony , my father got that radio brand new in the box when I was a teenager, and 61 one year old, my father just celebrate his 87 birthday on February 11 , he gave me the radio 📻, still kicking better than a brand new radio . Thanks 🙏 for the videos and for reviving in me such a bunch of wonderful memories from my youth. He used to own a Zenith Transoceanic , that one I don’t know the were about, but he got it when I was around 8 years old , also brand new , he was a fanatic of short wave radio listening, Grunding was one of his favorite brands back then. Miss those days so much .

You are one heck of a teacher! Enjoyed watching and learning. Thanks for your time.

You got a thumbs up from me for unsoldering that switch bank alone!

I love these radios. Great video Tony. Thank you.

Excelente Tony, he aprendido mucho de radios AM y FM con tus videos.

This gave me nightmares. I've often considered buying one of this generation of Panny's, but you save me. I am forever indebted to you Xray!

You will be a very good teacher thanks 👍 very much

Bought one new a long time ago. Nice little radio.

I’ve owned my RF-2200 since 1977, and had it recapped and aligned a couple of years ago. Keeping a dust cover on it is highly recommended. Also, tuning in SSB with the BFO is made much easier by gearing the main tuning down to “Slow”. As you discovered, this is one radio that one can safely say it makes sense to do a complete recap on. When I saw your first video, the telltale sign for me was how high you had the volume knob up. With new caps, this radio should have booming audio.

Great series, Tony! I just dug my 2200 out of my basement which I purchased over twenty years ago for around 50 dollars..... AM and FM work great, but sadly no Shortwave bands are functioning. I'm sure it needs a switch overhaul as shown in your presentation, more than I can handle in my "senior years" I'll probably use it for Am D'xing . Luckily it was stored with no batteries installed. I've been listening to an oldies station in Nashua N. H. AM 900. It's a 900 watt transmitter with some pretty aggressive audio processing and sounds great. Power for the station is 100 watts at dusk...

Back in the day, when I worked for a local NPR station affiliated with the public library, we had to align FM SCA "talking library" radios in a EFI and RF shielded room because the sets were cheap, extremely sensitive, and had little shielding.

22:43 That bandswitch, if you noticed, the black oxide is only on the outer edges, there where the contacts are in closer contact with the atmosphere because there are some holes in the metal casing of the switch. I noticed that always with the large R/PB switches from tape recorders too. It is therefore a good idea to stick some good sticky tape over these holes to close it off.

Those purple caps make a mess. I repaired a Roland drum machine that had many traces eaten away due to leakage. I replaced all of them on my Technics table and they all had fuzzy, green legs.

I’m sure the wax is there for a reason. For the factory to take the time to put it there, indicates there is a reason for it. You mentioned your hand was affecting the performance. So obviously this radio is extremely sensitive. The wax is likely there to keep atmospheric humidity (and it’s conductivity) off the sensitive board to help stabilize tuning.

Hi Tony, I have one of those. My parents bought it in the 80's when they worked in China, so they could listen to Voice of America. (That was before China began their Balloon messenger service.) It's not working, I suspect it is the "horrid switches" needing Deoxit. (I had to wonder if that was the issue with the xtal marker on yours not working, then working.) It really is a great radio, even with it's quirks. Hopefully, I can bring it back to life. The videos are of immense help.

Good job, Tony, on a service-unfriendly radio! They have used cost-cutting procedures with no shielding on critical circuits, and flimsy mechanical construction. End result is great, but with many work hours, I guess

Way to hang in there, on a tough job.

Great!!😊

I believe some yellow paint is in order, Tony! :)

Per the gentleman on "Low Buck Garage", "If you aren't having fun, you're doing it wrong". Were you having fun Tony? I guess I can't imagine any set of circumstances that would tempt me to obtain one of these radios. But maybe I just lack imagination . ..

I didn't expect to be visualizing a capacitor with a diaper on it today haha

Panasonic needs to get back into manufacturing these radios again with more modern circuitry......I miss them!!!

I'm doing one of these now. MW/SW was stone dead. Then I found the battery corrosion in almost the exact same place you did. A quick jumper between TR10 and L28 solved the problem. Still deciding on whether or not I will recap, as there are no obvious issues, hum or distortion that I can discern. I am seeing a bit of flickering in the dial lamps, all in time to the music that happens to be playing. Perhaps a power supply issue to unearth?

Hi, awesome video. I have a rf2200. FM and AM are good but i got only very slight noise on SW with zero signal. The tip of antenna was damaged. Any idea what could be wrong? I bought the capacitors to replace. Switches maybe is working. Thanks!

Wow! What an ordeal! I’ve got a ‘parts’ Transoceanic I would love to restore, but ouch, the thought of troubleshooting and repairing it is daunting to say the least, and aligning it? Well, let’s just say I think I would be looking for professional assistance.

Got any tips for the Panasonic RF-B45 and its keyboard not working? I treasured that radio until it quit on me 7 years go, then I bought another SSB receiver to replace it but kept the radio thinking it could be repaired. Many thanks in advance!

I am going to order new capacitors for my RF-2200 but I am wondering if it would be better to replace the smaller electrolytic caps (like the .22uf, 1uf, 4.7uf ) with ceramic caps? Any reason I shouldn’t substitute ceramics for those smaller values? Thank you.

Do you sell these devices? Greetings from Brazil, nice work with this device..

Hello, tell me, in the FM block, the L3 coil has how many turns and from which turn the tap comes, since I had it repaired by someone and the L3 coil was not wound as it should be and without a tap, but it should be with a tap

I am trying to make the adjustment in my RF-2200 but I do not understand in the MW-SW alignment in the step 1; tab Radio dial setting what does ' point of non interference' mean? I would be very grateful if you could give me some explanation. Thanks.

Tony... You didn't change the purple electrolytic cap?

I did. The video is not linear in its recording. Certain clips are out of order from the others.

Have you tried using an ultrasonic cleaner for the switch?

Yes. That was my first attempt. It didn't work, which is unusual. The only way was to disassemble it as you saw. Spraying it with deoxit would fix it for a while, only to have the issue return.

I have just purchased a RF-2200 it came with the usual issues, MW and SW did not work at all but it can be easily solved spraying contact cleaner in the switches. I have another issue that I do not how to solve it, the dial log shows another frequency that the one I am listening. Ex. Listening 1548 Khz shows in the red line almost 1600 Khz, How to read the dial on Fm? Do I have to dismantle the radio in ordenr to reach the tuning shaft and align the frequency? Thanks in advance.

What may have happened is the coupling between the knob and the switch may have skipped a gear. This can happen especially when you have the back cover off. I think I showed this in the video. You should be able to remove the rear cover and pop it back into place. I hope I didn't misunderstand the question, but that's what I thin k is going on.

It wold be great if you make a video with a full step by step RFalignment. I do not dare to make it according the service manual it seems complicated.

I pretty much covered everything in the video. The other SW bands are exactly the same as the first one, when it comes to the alignment procedure. I know there is probably some things I missed in the video, but feel free to comment, if you have any questions. I'll try to answer you to the best of my knowledge.

@@xraytonyb I have already replaced all rlrctrolytic cpas with fresh Panasonic and Rubycom ones but the sound is now too bassy and 'boring' gor my taste. I see in your videos that the main capacitors are Nichicon , brown is PS series but the golden I do not the series. I cannot identify the blue ones 100uf which brand are. Is the sound in your radio clearer or in the bassy side? Please . I fyou could tell me the series of the golden and the blue ones I would be very grateful. I have not started the alignment yet.

Digital tuning I'd simpler

Sir why Japan made the best radio in the world .
