UPDATE:

I was finally able to power up the chassis tonight, but so far the results were not good. The previously jumped fuses were not blown and of the correct amperage, so I thought I was in the clear. I checked all of the tubes (except the picture tube) and found 9 of them were bad, many of which had shorts. After replacing all of those I replaced the two 3-section electrolytic cans and powered the unit up on the variac.

I had read on various other posts that many of you do initial power ups without the high voltage section. To me this meant disconnecting the tube and removing the 6BK4 and 3A3 tubes from the high voltage cage.

Current draw was looking good up to 90 volts where I stopped for a second - only to watch the high voltage fuse pop with a nice blue spark. I assumed the high voltage section was isolated because I left the tubes out but obviously I was wrong. Any tips? Do I need to perform a short check around the flyback or was my leaving those tubes out a bad idea? Maybe I should have yanked the 1V2 and 6BK4 as well?

Anyways this is an early indication that something is wrong. Any assistance will be greatly appreciated as this is the most complicated radio I've ever seen!
