Single Ended Triodes (SETs), the ultimate tube lovers dream.

Re: For Kurt or ? input tube bias?

Thanks for the feedback. Part of my problem, I suspect, is that I'm trying to drive the heck out of my 300B to get most output. I'm using Valve Art 300B - C60's which can disapate 60w and a use a higher B+ and current. Mine is fixed biased at -93v for 74ma, 460v. I suspect it is the need for 93v p-p that is complicating making the driver work properly.

Any suggestions on how to drive this would be appreciated.
