6550 & KT88 - interchangeable?

[jandl100]

Well, are they? :scratch:

I'm happy to re-bias, but that's as far as my techie tampering goes! :)

Is there any danger of something going phut or, worse, bang! ??

I currently use, and the amp is designed for, KT88.

Depends on the amp design I should imagine. Which amp is it, Jerry?
