Yamaha YPA-1020 help needed
Hi,
I have a Yamaha YPA-1020 of which channels 2+4 are working fine, but 1 and 3 are having problems. 1 is much weaker, and 3 slighlty weaker. On top of that, both of these channels don't sound right, muffled. What could be the cause of this ? Capacitors in the output section ? I only have the service manual for the smaller 4 channel 720, the 1020 is a little different though. Fred |

You need to compare the signal at corresponding points between good and bad channels to see where you lose the signal.
