6550 EH direct replacement for KT88?

[Axtman]

I have a Sunn Coliseum PA amplifier that I am restoring. The schematic indicates KT88 output tubes. Can I use 6550 Electro Harmonix tubes?

Other advice would be appreciated on restoring this beast.

Yes you can. Any of the current 6550 or KT88 types would be fine. Personally I like the JJ KT88 in my Sunns.
