Hi Myles,I appreciate your response.I went to your website and looked around again(I had been there before but I went back in case I missed what I was looking for).Checked out your son's site too. I think it's great.Anyway,I guess I need to re-state my
question better.I'm interested in tube substitutions
OTHER THAN the 12AT7's and 12AU7's.Specifically the 12BZ7 and the 12AZ7.I've had great results playing with those tubes in the different slots and I don't know anything about them I've searched the net high and low and I can't seem to find the information I'm looking for.Have you experimented with these tubes or can you point me in the right direction?Thanks,Ricky
