Ampeg SVT Classic goes into standby on its own

[Gregg]

Check out the schematics from the link earlier and check the voltages on the fault/standby circuit to make sure it's OK.

Sorry for bringing the old thread back... I'm now searching for a reson why my SVT-CL wont EVER come off standby... I've been diggin it for some time now. At first I blamed the relay, then in general, AC Board, then it lead all to transformer failure BUT I have SVT-AV from exact same year so I did some test. Swapped A/C board - no success, so AC on mine is fine. Then I connected CL preamp to AV, and guess what, AV won't come off standby, so the problem is somehwere in the preamp area and it's not the cables (they were run from AV).

Now to get things together:
- after power switch red light is ON
- no relay click after power switch
- no blinkin LED on the front
- standby switch is tested and OK.

Any thoughts?

Hi, welcome.

First, please start a new thread for your amp, it gets confusing talking about more than one unit in the same thread.
