  Often one or two sections are low voltage, used for cathode bypass, and the remaining sections are higher voltage.
  
  If so, you maybe able to use a dual or triple section for power supply filtering, and use small single caps for the cathode bypass.

  I may have an NOS Sprague or Mallory can in cold storage. You are free to try it, if you wish.

    Thanks FenderLover! It's 350/350/450/450 V. If you have one, I am willing to buy it.

      I'll check my stock tonight. But, the CE cap from Antique Electronics would be the freshest option.

      If he doesn't have it and you want a twist loc this is probably your only option.
      
      Honest amplification is better than excessive 2nd order distortion anytime.

  You can use a quad 50 twist loc,or use an 80/40/30/20 twist loc. You can go higher than the original values and its recommended that you do.For the 60uf,you would have to parallel in an additional 10uf cap in parallel to make up the 60uf..This is a very silly and more costly approach tho.
  I would get a dual 100uf and dual 50uf and put those in instead.You take the old cap out and just glue in the dual 100uf in its place with some amazing goop.Then glue the dual 50uf underneath and hook both caps up..You have plenty of room and your amp will sound a lot better.
