Some of you may have been following my other posts on this and the DIY 2x15. I decided to do something different instead of restore this gem. Cheaper! Just finished this "Rat Rod Ampeg V4B". I got the guts out of a VT-22 (combo version of the V4), chopped the cabinet into a head box, converted the relevant components to V4B specs (the bass version), replaced every capacitor and resistor, converted the output stage to take 6550 tubes (formerly 7027), put NOS tubes in the pre and a matched quad of Svetlana's in the power section. Set the bias just right for plenty of clean headroom. I gigged with two guitars and drums and only had the gain on three (there's no master). Most all the tech work from my friend, George. Matching 2x15 cabinet to come.
