Vintage Tube Amp.
Tested/working, with little hum.
Some controls/switches may need cleaning (DeoxIT or similar).
For best results, power supply filter capacitors should be replaced.
All tubes test good.

4 same code 1960s RCA 12AX7A, 2 NOS same code GE 6GH8A,
and a new Sovtek 5AR4.
Circuitry appears original and unmodified.
This should be refurbished before regular use,
there's no guarantee capacitors are good.
Please ask if you have any questions.
