Glad you got it fixed, and thanks for sticking with it and talking everything out. I had nothing to contribute, but was following the thread with a lot of interest. :smiley:

Thank you John! We are both still noobs compared to guys like Sluckey. I am truly amazed at how knowledgeable some on this board are. They know tube amps like they all invented them. Amazing board to learn!

Can you believe that this topic has made me turn into a level 2 on its own? I have learnt a lot on this one. Really a lot. I have learnt more through this single amp and this "simple issue" than through the 15 previous amps I built all combined...

I may buy a Hoffman Tweed Deluxe OT instead of the Classictone if Bruce doesn't send me one new for free... What do you think?

Many guys here have used them in a lot builds reporting very good results. I have a few laying around here that I haven't used yet, but I bought them because of what others have reported after using them. Than again there's quit a few places out there to buy a good OT.

Price for shipping might be a - big factor - depending on what country your in.

Glad you found the problem.  This is the exact reason I bench test all new power transformers for proper voltages and do turns ratio tests on output transformers before installation. It only takes a few minutes  and you know what you got.  QC is not what it used to be.  If I take in a non working amp that looks to be hacked, I always test the transformers and check the mains fuse for proper size. You never know what a hack has put in there.
