OK here is the issue on my 5e3 build I am going to the amp tech I go to tomorrow to get some more tubes for this amp either a 12ay7 or a 12ax7 depending on what sound I prefer I know the 12ax7 should give more gain. I have two 12ax7s in the amp now and if I switch them from V1 to V2 the one that was in V2 for the half preamp gain stage and half PI starts out loud and then just fades down to nothing. If I put that funky tube in V2 where It was on the old amp chassis (Preamp/PI) the amp works but I am sure I am not getting the gain this amp puts out as it stays pretty clean. I will know more tomorrow when I swap tubes, but my question tonite is is that one tube faulty to do what it does in V1? (Preamp stage) I am guessing there is something screwed up with that tube or at least part of it.
