Wow, that's a really nice stereo. I'm glad that you were able to save it from the unforgiving clutches of the landfill.

@RetroCaptain Actually there was, in the 1950s before FM multiplex was invented a method of transmitting stereo was one channel on AM and the other on FM.

What a marvelous thing you've done--restoring that wonderful stereo amp.
I have a Sansui G7700 that both left and right channels have once again gone out. They tell me the parts are no longer available, but I hate to get rid of it anyway.
Hopefully one day I'll come across someone as knowledgeable as you to fix it.

People are so numb when it comes to this stuff, why would you just throw it out? Glad you staved it Chad

Magnificently constructed receiver! Big output transformers and nice Nuvistor FM front end!

What were the advantages of the Nuvistor? Was it a space saving thing or a performance thing? Speaking of dumpster scoring. I found 48 Ck722's and 8 Nuvistor 6CW4's a couple of years ago at a retired Defense plant engineer's trash pile. I continued to go back every week. Turns out the surviving son lived next door to his mom ( the wife of the former worker). In his spare time he was sorting through the stuff & organizing ( baby food jars etc.). Was pitching out boxes w/ mice droppings.2Bcont.?

@RetroCaptain Yes, the Pilot 602 has an option on the selector knob that allows the AM & FM Tuners to play at the same time simultaneously. Do some more research on the Pilot 602 you will see what I mean. I can eventually make a video of it playing both bands at the same time for you but that won't be for a while as I have to dig it out of storage.

@ShitFromShinolla Good day, There never was such a thing as "Stereo broadcast reception, via use of both AM & FM bands at the same time.... he is perhaps like the singer in this vid who claims "Ocean front property in Arizona". It was a fancy fad back then..a neat looking style, like dual exhaust on an automobile.. If you could put a vid of your receiver playing AM/FM at the same time, let me know.. The multiplex unit enables your set to play stereo FM signals. There used to be AM stereo.

cool. that is a EM84 magic eye, right?

Wow!! Never saw anything like this. Bless those guys at the Sarnoff center back then.

Armstrong would be proud! The FM is very much noise free compared to the AM! Too bad that so most of the programming on radio is crap!
