Yamaha CR-800 meter lamps wont work.
I recently picked up a super clean CR-800 and of course all of the lamps were out. I got some LEDs on ebay and started swapping them out. When I turned the power on, the dial indicator lamp worked, but all 3 of the meter lamps did not. I can't get any power reading at the meter lamp lugs... -

Yamaha CR-800 Faint Channels
Hoping someone might have some sage thoughts on a CR-800 I've been struggling with. This unit had no sound when I got it, but I have since worked through to almost bring it back to life (with much appreciated guidance from avionic last year). I have replaced fusibles and recapped the PB, main... -

Yamaha CR-800 weak right channel
My 800 sounds weak from the right speaker. I've swapped the speakers, and ruled that out. The volume is about half of the left side. Sometimes it comes up higher if I flip the High-Low Filter switch a few times. I'm wondering if there are some things I can look at before I give in and go see the...- MiKokomojoe

Yamaha CR800 No Speaker Sound, Headphones work
I have a 1970s Yamaha CR-800 receiver. I was swapping out speaker wires to connect a 6-channel A/B speaker selector to the stereo and I left the receiver power on while I was doing it. The speakers were working while I was doing the work, then they went silent. I assume I shorted something out...- YamahaCR800

CR-800 Ph-oh-no!
In my quest to cure a noisy RIAA stage, I did discover a fractured joint at D401 on the so-called EQ Sheet. (PITA to get to, mind!) Now, in this case, somebody before me had fitted a 330R, 5W resistor in the supply line - non-original and not shown on the schematic. Off-load the supply does...- cleverdick
