@daveyf Your observation makes sense.
Regarding: Was your amp originally designed ( circuit wise) to run 6550's?
I would expect so as the original M120 monoblocks were based on 6550/EL34/KT88 tubes.
KT120 back to 6550
@daveyf you are talking one point of the whole story. Which is the design of amplifier for specific tube. The other point we need know is about the feature of individual tube. 6550 is better for vocal for sure than kt150. Kt150 might be good at both end but not middle. Kt120 is in-between kt88 and kt150. |
@runwell "6550 is better for vocal for sure than KT150"--where do you get that from?? "KT150 might be good at both end but not middle"---Huh???

@daveyf from my listening and from others experience. Don't you tell me your idea is from the magazine. |
@runwell No, my idea is from actual listening experience with my own amps and in my system, or with friends amps who are using KT120’s. What amps are you referring to? |
