1966 Ampeg J-12-D Jet


A small Ampeg J-12-D Jet amp from 1966. This version has a solid state rectifier and stays clean until about halfway up. Uses two 7591 power tubes and two 6BK11 preamp tubes. It has great overdrive sounds but supposedly the earlier Jets with 6V6s are more desirable. There is no intensity control for the tremolo, but it sounds just right to me.

Power Amp: 2 x 7591

Preamp: 2 x 6BK11

Rectifier: Solid state

Speakers:  1 x 12" CTS

Effects: Tremolo

Controls: Volume, tone, tremolo
