This is a low watt amp, maybe 5watts. I bought it to play the harp through, but I have been playing my new pink paisley tele through it. The tele barely gets the amp to distortion, though when I picked it up the previous owner demo'd it with a Les Paul and it distorted nicely. It is an Airline 62-9022A made by Valco. It looks to still be all original including the two prong cord. It has two inputs though I can't hear much difference between them. A tone knob a volume know (which turns on the power), the power light and then the fuse. The tubes are 12AX7 pre-amp (just says USA 12AX7 no other markings), 6V6GTA Power (RCA USA), 5Y3GT rectifier (RCA USA). There is also a metal canister thing between the power tube and rectifier. The speaker is a USA Jensen 308Y21D1. The power transformer shows no markings, but the other transformer (not sure what it is called) says T2640, 524 65 37. Looks like someone taped over a sticker underneath the chassis so I'm assuming it is a serial number, but not sure, 1-44291 Here are photos of the GUTS: I got a little surprise when I opened it up The inside is very clean.
