Title: Twin Reissue Bias Pot
Post by: duke of earl on April 19, 2010, 10:32:06 pm

I have a 65 Twin Reissue on the bench and was wondering about the bias pot. Is this a true bias like on the original?

yes, like an AB763 except the bias voltage comes from a separate PT winding, rather than a tap on the HT winding.
