This sad little amp followed me home.

...It's 135 watts ultra linear transformer clean...

Just to note that these late 70s Fenders operated a 'distributed load' arrangement with screen grid taps at about 12.5% so very close to regular pentode mode; whereas UL screen grid taps for 6L6 would be at ~40%.

The amp is a 1977 Fender Vibrosonic Reverb. As you know, Fender made 5 amps with the same chassis. They just changed the speakers, cabinet and faceplate.

Those amps are:

Twin Reverb (two 12 inch speakers)

Vibrosonic Reverb (one 15 inch speaker)

Dual Showman Reverb (head, no speakers)

Super Six Reverb (six 10 inch speakers)

Quad Reverb (four 12 inch speakers)
