Here is what I can figure out for my venture into a DIY KT88 type PP amp with reading the archives regarding new manufacture tubes.

I believe the issue of 'what is best' of new manufacture tubes (not including the undisputed EI KT90) is for the most part the tube that compliments the amplifier individual sonics & speakers. My less than perfect conclusion is as follows:

#1- Undisputed Best- Most Expensive
EI KT90 type 1 or II (supplier is J. McShane)

#2- Excellent & Low Cost- Perhaps the best Bargain Priced Tube
Russian Wing 'C' 6550

#3- Good Tube
Electro Harmonic KT88 as a low cost alternate that J. McShane can live with in a Citation II amp.

#4- Another Good Tube
Valve Art KT88 that does not seen to have near the following of the EH KT88.

Be forewarned, I have zero background on the 6550/KT88 tetrode based amps. If I had owned half a dozen and rolled plenty of tubes plus upgraded components, I could come to a conclusion of a tube that consistantly outperformes the rest. I believe J. McShane has done that.
