I had a chance to play on a mint original Ampeg V-9 guitar amplifier with distortion. The crunch on the distortion was alive, rich, unique and the power through a 4×12 V-2 cabinet was face melting. The original cabinet had 9×12 speakers in upside V formation and one could only imagine the full fury of 300w Tube power through that monster. These original Magnavox USA tubes all pegged my century 100 tube tester to max power. Small little fires glow in them.
*For some reason I decided to re-cap this unit. Feelings were never the same after the sound changed.
