Found another use for old SS amp PTs

Post by tubeswell » Mon Nov 13, 2017 4:07 am

AC source for transformer testing using an old PT with a 500VA rating (50VAC secondary) salvaged from a SS bass amp, coupled to a $10 rheostat (1k 25W) in a box. Output goes from 0 to 50-VAC

I'm glad you posted before I throw out my wrecked metals bin :wink:
(too bad I lost this rheostat, though)
