Here's one of my "biggies" that I have had since 1989. I haven't played it in few years so of course it needed to be brought up very slowly and the lightbulb too. Just needed the first cathode cap, otherwise all clear. Regulating the voltage to 115 I got to 565 volts as the heaters reached 6.3V. Back in the day that's about what the wall would have provided. This amp would have predated the Monterey amp of Jimi's. The way the PT was mounted with the extra mounting ring on top makes me think that the Drake 1204-43 hadn't been introduced too long before. The missing brass vents indicates they were out of them at the time, so they left it unfinished, though the slots were cut in the head cab. It also seems to be an early appearance of the square red pilot light. Chassis hole only just fits it whereas the RS light would have required a larger hole. The pointer knobs are vintage but probably not original, but maybe it could be possible that in Marshall-fashion they were out of knobs AND vents.
