Post Subject: A “full power undistorted bandwidth”.Posted by Romy the Cat on: 2/21/2008

Jim, the “full power undistorted bandwidth” is the only bandwidth that counts, at least as I understand bandwidth. The 25Hz to 19kHz is it what would expect from a regular SET if do not spend a LOT of money for output transformer. Your amp is not SE amp and I do not know how bandwidth works in PP amps. Theoretically the no gap transformer should be helpful, in bass region but in practice I feel that a use a DC blocking parafeed capacitor overrides the no-gap OPT bass advantages. I am very much not the person who can credibly talk about amplifier topologies but a need a capacitor and transformer in sequence just does not make sense to my view of common sense.

What is actually found interesting to me, Jim, is that you are trying to make an amplifier, using a new to you solutions an active element without very organic incorporating of actual listening assessments in your design process. It is what I am unable to do, in fact I feel that listening evaluation are the only objective measurement that we have…
