Food for thought…I found some forums saying that using EH 12ax7 in the V1 position sometimes leads to failure. Is it possible my 12ax7 is bad? Sorry I keep posting, I am just home working on things now so while i have the time to post I will! I happen to be using the Electro Harmonix tube as V1.

So yes the voltage across the 100k doesnt drop very much. 300 to say 280-290 seems to be what I am seeing as measure to ground at the star ground.
