Help powering on a A0-29-1A

[Fastback4]

This is all of the items I was able to salvage from this Hammond M3 organ. I will try to post the pictures here. The amplifier looks like an A0-20-1A, form A1, s/n 52541. I cleaned the amplifier best I could and had to put another power cord on it. I would like to be able to power on this amplifier just to see if all the tubes light up. I see where these amps don't have much value, working or not, but I'd still like some instruction to power it up.

I don't know what your expertise level is, so pardon me if any of this sounds blunt. Just because the tubes glow doesn't meant the amp works. Unless you have done any work under the chassis, tested components, replaced the ones in need of replacement, it is not wise to power this on with tubes installed. You could pull out the rectifier tube and the 6V6 tubes to just see the other tubes glow. If there is a short in the rectifier wiring or in the tubes, you may experience problems that could overheat and damage the power transformer. If the rectifier and 6V6 are installed, the amp should have the inputs grounded, and a speaker or dummy load attached to the speaker output. Refer to the Hammond service manual for more information. Terminals A and B are the main signal inputs, and should be grounded.

I would recommend having someone qualified in tube electronics to check the amp and tubes. If not, consider it salvage / parts, and don't attempt to power it on until it's had that treatment.

I will try to sell all of these parts as is no warranties implied. Thanks for the advice.
