Yep, C100 and C101...I restuffed the bakelite block with safety caps:
It's always been my understanding that all 47-1230's suffered from hot power transformers, but apparently not. I don't know why the difference. Perhaps whatever is causing your FM/phono volume problem is related? All caps and all resistors have been replaced in mine. Initially I installed an 18 ohm, 50w on the back of the chassis to drop the AC line voltage, but it became excessively hot and caused the chassis itself to be hot. So that's when I went the bucking transformer direction.
