Alpha Voltages

[Valvehead]

I need to know what are the operating voltages on this amp. Its a Alpha Slave 100w power amp .

the ac out of the trans is 64v

and the DC out of the rect is 46V.

Is this about right for these?

I dont have a scem yet.

Assuming your 64VAC is center tapped with center grounded, then 45-46v is the DC I'd expect. 64VAC CT is really 32v on either side.

ok, thanks.


look like the power switch was the only problem. I ran a mic thru the amp and it seems ok .
