Extremely rare Ampeg Jupiter II rebuilt from the ground up. The top preamp features a normal and vibrato channel and has been completely re-capped. A control was added for tube driven spring reverb on both channels and replaces the original "stereo" input. The true Vibrato has a liquid/leslie like quality to it and nails the "Lucy In the Sky" intro, or can be switched to a typical Tremolo like effect.


The lower power section is a scratch build adapted from a 60's era PA chassis, currently running a pair of classic coke bottle 6L6G's at around 18W (300V plate with fixed cathode bias) into a 12" speaker, has the power supply and tube reverb circuit, and a multi-tap output transformer.


Everything is housed in a newly built tolexed cabinet. The amp is fully hand wired with a total of 8 preamp tubes (5 up and 3 down). I'll be happy to answer technical question, but otherwise the pictures tell the story for those interested. Schematics are included.
