Grew up working in a TV shop, and was servicing tube amps for years before building any. I only play enough chords to test stage amplifiers. Never keep a guitar or a big amp around here for long. Last instrument amp I bought new was a Blues Jr. Got lots of tube test gear, some iron, some parts, and a few tubes. Couple of small Watt single-ended PA chassis on hand at present, great for rewiring into guitar practice amps. Been pondering this Sony stereo tube tape deck for hacking, too.
Presently listening to a stereo push-pull 11 Watt integrated amp breaking in a new quad of Czech 6L6's, pushing Vandersteen 1's. Its sweet.
What are you wanting to build? You must enjoy all styles of playing, you have 4 really different axes sitting there! Looks like maybe a silverface Fender?
