Got the new tubes in it...TAD 6L6's Short Bottles/TungSol 12AX7's and got it biased up. Sounds great..definite improvement. I didn't realize the previous owner had swapped one of the 12ax7's for a 12AT7. I put the 12ax7 back in there and loss some headroom but the amp seems much more responsive and punchy. I'll stick with those.

I sent Louis Electric an email the other day and Lou Rosano actually picked up the phone and called me at 10pm. I had some questions about tubes & biasing the amp and he got me on the right track. He told me to start around 40ma and tweak from there. Btw I also bought the bias scout kit from tube depot and it works very well. It knocks everything down to mV's so you don't have to mess around the high voltage. I went ahead and took direct measurements to verify it wasn't skewing the readings too much and it was dead-on. Got 49mV using the scout and the direct measurement was 490v. cheap too/$20...just gotta have the patience to put it together...
the tads are nice. that is what two rock uses. i am surprised you had to bias, the original tweed deluxe is a cathode bias.

Yep I'm liking the TAD's a lot. Very similar to SED's... which I usually use but have doubled in price since the last time I bought some. $100 per pair? wtf....

This amp is "based" on a 5E3...but is fixed bias, using 6L6s, custom wound transformers. It's a very beefed up or "clean headroom" version of a 5e3.
