What is the exact make/model?

timwebb · 27th November 2010, 05:43 PM

memphis 1000.d the silver one.

Perry Babin · 27th November 2010, 07:52 PM

I'm assuming that it's the 16-st1000d. Correct me if I'm wrong.

Does the relay engage?

Is there any DC on the bussbar that's between the transformer and the filter caps?

timwebb · 27th November 2010, 10:29 PM

yes the relay engage.and there is no dc on the bussbar.

Have you operated all of the switches and pots through their entire range?

If so, did the amp ever produce audio or any noise?

timwebb · 27th November 2010, 11:25 PM

YES I operated the nobs but it never made any noise
