need advice about an older amp - lazydays - 07-30-2010
I have an Accuphase E-202 which was rebuilt in 1996. I was listening to music a few days ago and heard a "pop" sound and the speakers cut out. If I turn the amp off and then back on I do not hear the customary "clunk" sound that follows. I have tried pushing the reset button in the back with no luck. Any suggestions?

I think I have said it before, when something like this fails, there was likely something else already wrong with it and the current problem finally took it down. I would guess there is an internal fuse somewhere in addition to the circuit breaker. If there is no fuse, then look for either a bulged electrolytic capacitor can or a blackened transistor in the circuit close to where the power comes in.

What Fill said, with the added note that somewhere there is a component that lost all of the critical material that is the active element in all electronics......
Smoke. :biggrin:
(You may want to check your speaker fuses... The electronics repair sequence is:
1- Check it's got power.
2- Check all connections.
3- Check all fuses.
4- Look for signs of heat damage- scorch marks, smoke smell, bulging capacitors, etc.
5- Scratch head and start tracing the circuits.

You DID get your money's worth out of the thing, ya know? ? ? ? ?
I have an Accuphase P-300 that I NEED to get rebuilt. Currently saving up for the rebuild and the SHIPPING . . .
