This thing had a lot of bloated body bag caps hissin' fit to bust, and two old, decrepit resistors in the left channel causing some thermal issues with its outputs -- like the kind if you ran it for about an hour you could use the output transistors as a cigarette lighter to fire up your Virginia Slims...like that kind of thermal issue. Which was kind of strange about the resistors, on account, when they were cool the olms were an acceptable 10.5, but when they started warming up a little they jumped to 15 olms which was off biasing the outputs and for solid state that's pretty critical. Well, I got that all done and replaced all the blown lights including the radio needle bulb, and now at even 50% this thing can raise your roof! That's still pretty strange though about the resistors, they normally just usually creep up in value not fluctuate.

That is one gorgeous piece of hardware! I salute your skill in bringing such a majestic beast back to its original glory. My grandfather had a Marantz similar to that, although I'm not sure if it was the same model. They just don't make audio equipment like that anymore and the pity is that in our digitized, bass-boosted, over-processed era, people just don't remember what real audio sounds like anymore. I have a couple of Kenwood receivers from that era but nothing on that scale. I reconstructed my college era system last winter and when I turned it on for the first time, it was a very emotional experience. I, too had forgotten the richness of '70s audio gear.

Thanks Edgar!
...And by the way you got that RIGHT!!! Such as that hot glue state, cheap Crosley Cruiser Crap and dime sized precision, China-mart made DC motors, or I-Phone mini micro mono speaker trash like that! Truly, we are at such a generation where they do not possess the slightest inkling of the vast richness of what Ultra High Fidelity has to offer. The 50s, 60s, and 70s had some really great stuff which was designed to be repaired, but the equipment, nowadays, (if you can even call it that) is designed to fail in quick order and be completely replaced with another piece of low fidelity trash which will EOL itself just as fast if not sooner! I was thinking about putting my '59 Magnavox on, which I most sadly found with a bad AC motor, but happily I found a replacement for it, and let me tell you, that thing can raise your house to the ground!
