- I regret to inform everyone that Chris Cuff has passed away after the making of this video. As of this writing, his website and RUclips channel are still up. His contribution to this hobby is appreciated and for that, he will always be remembered. Below, are some websites for AM stereo:
Chris Cuff's AM Transmitter: www.amstereo.or...
Meduci AM Stereo Decoder: meduci.com/

Thanks so much for making this video. That is a awesome looking receiver and it must sound great in AM Stereo. I got my Chris Cuff's AM Transmitter about 3 years ago. Since then I have gotten a few more AM Stereo "C-QUAM" exciters and AM Stereo "C-QUAM" receivers. I just cannot get over how good AM Stereo "C-QUAM" sounds. I know more about it now then I did back in the AM Stereo "C-QUAM" heydays. Better late then never. Again thanks for posting. I need to try and convert a AM Receiver with a Meduci AM Stereo Decoder. Right now I have a 1992 Chevy truck with AM stereo, a Sony SRF-A100 and a Sony SRF-A1. When I listen to AM Stereo "C-QUAM" with head phones, it knocks my socks off!!!!!
I love to have a transmitter in C-quam AM station, just for fun and remember the 80s, how cool the stereo was in AM mode
Congratulations on another job well done! I learned good information from you again! In regards to the rule of really avoiding modifications to the original and vintage specifications, I agree. I have the same rule on my own vintage equipment. I sometimes modify areas of the equipment that showed to be problematic after a few decades of use, such as trying to replace ALL electrolytic capacitors in the audio path w/ film ones (where possible) and installing better heatsinks and more robust components in overheating power supplies but, same as you do, my modifications are 100% reversible and I don't make holes in the boards or the chassis of the equipment -- also I try to replace incandescent bulbs with LEDs -- they usually consume less than 1/10 of the power of the bulbs and keep the equipment much cooler inside... some vintage pilot lamps consume more than 1.2 Watts!
Beautiful receiver. Tony - thank you for another great movie. These black capacitors are the same nightmare for Sansui as the orange ones for Nakamichi. I greatly respect your decision to repair the equipment, but without drastic modifications. It's a pity that you made the decision to mount LEDs instead of bulbs, the more so that the diodes you mount do not provide an omnidirectional illumination, but only directional. After all, a huge respect for the passion, the work put in and the restoration of another beautiful representative of Hi-Fi audio to the splendor.
As always, I send warm greetings from Poland, waiting impatiently for new materials.
What a great video Tony and there is certainly alot of electronics packed into this but for the specs and performance of these models it's totally worth it being overkill. Those blag flag caps strike again! I wouldn't mind betting someone adjusted that 455 kHz trimer in the past to attempt to get it working since you found it screwed right up. I like how you fitted the AM stereo decoder board without disturbing any of the original areas of the inside. A friend of mine has a small AM stereo transmitter being fed from a music source and it sounds pretty good. Wouldn't mind hearing on this TUX1. Keep up the good work!
I first heard AM Stereo in 1985. Chevrolet factory stereos had it.
Thank you for another awsome fix, I so envy your knowledge of these tuners and amplifiers. Would work with you for free hoping some of your knowledge would rub off onto me.
Thanks for sharing.
Great stuff Tony!! Damn black flag caps strike again 'eh.....Nice job on the AM stereo, I am very interested in the AM stereo, but I can guarantee there are no AM Stereo stations where I live!!
Nice fix and upgrade on that beast of a tuner! Too bad KDKA stopped broadcasting AM Stereo in 1997 when they moved to their new transmitter site, you can get that station on your fillings!
Nice job Tony as always! 73
Thanks Tony!
Thanks Tony
For an AM stereo signal generator, I wonder if a cheap fl2k adapter with a short piece of wire stuck in the connector and placed next to the radio would work well.
I wonder if sensitivity would be improved if you could add a IF amp in front of the detector. The Sansui output may be a little low for what the adapter is built for.
I just had an idea for a video - Antennae! How to tune them, how to impedance-match, etc.
If we could of found a fa-7 antenna that would of been great. Alas as tony says they are unobtainium
30:30 - How about a really good roof antenna?
gotta love these black caps luxman had the same problem
Yes, these and some old RIFA caps are like the "glue monster" on the PCB shown in some clips.
Do they sell affordable licenses permitting shortish sampling of broadcast audio?
Look like servo couplers on CNC machines. I've replaced a lot of those over the years in my CNC programming days. I was the lucky guy who was the best mechanic in the shop so I involuntary was volunteered to do repairs LOL. I like electronics much better, a lot cleaner.
Tony! I have a 1 : 50 Lost in Space robot.. part of a kit for the whatziss mobile.Built it me own darn self. I have subbed u a while
27:40 - RUclips has library of royalty-free music to use for demos!
tbh... I am guessing at scale, and I only know that 460v really hurts..... twice! I saw lighning! and spent 20 minutes afterward. saying "oh f**k for 15 minutes while trying to light a cigarette
So some numskull has been at it with a screwdriver and should have left it alone but some people will not be told.
Can LEDs harm a person's eyes?
It could, like an incandescent or fluorescent light could too. An ordinary LED, such as those used as pilot lights on the front of the sound equipment or TV, or those used in VU meters or spectrum analysers won't hurt anyone even in you are in front of the LEDs for a long time or "forever". They are usually red, green, orange, yellow, blue or white. They usually take between 1.5 VDC to 3.5 VDC and take about 20 mA or less, so the power dissipated is less than 100 mWatts. It won't harm anyone. But a bright LED flashlight in one's eyes for a long time will likely cause eye problems, like any other type of bright flashlight would.
