I went to look at an amp tonight that had the original (1997) Mesa Boogie 6L6 GC powertubes in them. I noticed that they are kinda 'bulb-like' and not a straight cylinder like most tubes.
One of the tubes was microphonic and I know I can't just replace one tube.. at least two so do I:
A) Replace all 4 power tubes
B) Replace 2 outer power tubes (the one that was bad was on the far left)
or
C) Replace the outer tubes with EL34 tubes (I have 2 of them laying around).
What would the advantages/disadvantages be to each?
Thanks for all of your help!
