So the plan is to work on this amp and getting running proper over the fall/winter for a special event in the early spring. I havent done anything with tube amp electronics before so I'm reaching out on here to experts for some advise on where I should start. 

My own thoughts are: replace electrolytics and then slowly ramp the amp up using a variac over the course of a whole day then to play it, IDK if this is a good idea or not so yeah, looking for any and all tube amp advice!

Side note been chasing the Jack White sound for years with Fender amps and a big muff, this is the final piece of the puzzle aside from a WH-1 :) !
