Recommend 300b tubes for Frankenstein Amps

Brf
I've had the Victory IV's for almost a year and I have no desire to get ride of them. I was using them with a well known 300b amp, which I sold. I purchased a Coincident Frankenstein amp and the speakers sound much better . Then I purchased coincident Extreme power cables and rca interconnects and I can't believe how much better everything sounds. Never sounding harsh very well balanced sound from top to bottom.
If you purchase the victory IV's and you don't like the sound it's not the speakers.
I think Coincident is the best value for the dollar !
Israel is always quick to respond to emails.
Hope this helps.

I don't disagree about Coincident's being one of the best values in hi-end. BTW if your system requires more bottom end and dynamics, I really like the EML 300B - XLS, this is the tube I use.

Unusual, unless something wrong with the plate plate voltage or the bias voltage/cathode resistor.It is a circuit problem not the tube.
