I have a Prima Luna Dialogue Premium. I too run four 7581a power tubes and love them. Better bottom end & sweet midrange than el34b they replaced. Not as much power as gold lion kt88.. but more musical imho. I do not feel the need to invest in 150s.
Tell us about your KT150 experience
By now, there must be quite a few folks who own amps that utilize the Tungsol KT150 tube. ( I own a pair that do).
As such, i would like to hear the experiences that you folks have with re-tubing the amp with new KT150’s...what dealer did you buy from, how well were the tubes matched, how long have they lasted, any problems with the tube...new set or old set? What amp(s) are you using them in?...and lastly do you believe that they are superior to other Pentode power tubes...and why.
