Nice! Same... I collect "vintage" tube amps (90's music equipment is now considered that... Damn I feel old...)...Typically Mesa Rectifiers, Marshalls, but have a nice first year production Blackstar Series 1 100w head and matching cab, too. Some I've had since new, some are recently additions now that I'm no longer a Poor.yes sir, I pick around a bit. got an old '84 les paul custom and a 1937 martin d28 replica.
Hang onto that old Gibby, those things are going up ridiculously in value. I've been wanting a 69 LP for a long time, but the prices are too high now. No way in hell I'd pay $20+K for a guitar. Amps is already an expensive enough hobby, because most people selling them know there's something wrong with them, and then rip you off, because they're too cheap to send it to Mesa to get it fixed, so they just dump it off on someone else for current market value.
I like to get them for a good enough price to comp the cost of repairs, buy it, send it in & get Mike B. to fix it, then you have an amp worth what you have invested in it, and better than when you first got it. Hell, I just fixed a pretty rare one myself this week. I've always soldered, but never soldered a PC board before, but I fixed it, and it works perfectly now. All it needed was 2x $0.20 each high-end metal oxide 1K 2W resistors soldered in to replace the 2 burnt-out ones. 15 minute job saved about $500 on the amp value alone + whatever repairs would cost (guessing another $250 or so).
