Analog Audio Repair

This vintage RCA vacuum tube preamplifier was missing it’s power transformer.  Fortunately I had the schematics and a transformer that would fit the bill.  A couple power resistors were required to get the voltages spot on, but in the end it worked out well.  The unit got a full re-cap and a fresh set of New Old Stock vacuum tubes.  The new owner even received an original manual!
