Many of the older 6550 based amps cannot accept the newer KT120's. Presumably, the new KT150s would also be incompatible as well. So, to keep these amps alive, i think we will need to keep at least the 6550's going.
Do we still need 6550 or KT88 tubes?
I would like to learn your opinion and experience with KT120 tubes.
Considering that KT120 match 6550 or KT88 based amp (is a direct replacement), how do you like the sound of KT120?

Do we still need to pay for NOS power tubes?
BTW at the moment a KT150 tube is announced. Should be even better than KT120 and could be interesting upgrade for current KT120 owners.
