I ordered two ECC832 preamp tubes for my amp to lower the gain. Man I gotta tell you, I am liking this! Now I can turn the gain down to a reasonable level and play. And there is no loss of high gain, their think will get with the program when I dial up the gain. This thing sound a bit like the Hotrod Deville tweed 410 I tried at Guitar Center and the deluxe. This amp has such a cool blues tone to it. Its hard to believe its this nice without a pedal or something. I think I am gonna try the whole retube kit with the gold pins. They say this makes it smoother, I guess we shall see. Really starting to love this amp the more I play it!

I just read about Yellow Jackets the other day. Interesting concept. I was wondering how come someone hasn't marketed an adapter that allows you to use two different kind of power tubes, like say 6L6's and 6V6's where you flip a switch and change between the two. It would be cool of you could setup a pedal to control the switching but I bet you would need to shut the amp off before switching, which would make it impractical. But then again, I bet someone could figure a solution for that too.

Another tube to consider is the 5751 (in place of the 12AX7 at V2). This has a gain of 70 on each triode (in place of a gain of 100 on each triode in the 12AX7). Legend has it that Steve Ray Vaughan used these.
IMHO the gold pins would not affect the tone at all, but might give a more reliable electrical connection in the (very) long-term.

A few weird things with the triumph though, the laughable low value of the screen grid resistors really scares me.....and the ridiculous high value resistors on the control grids already on top of 220k grid leaks.....coupled with high B+ 6l6s were getting hammered in those amps, they didn't last long either....but man those amps really kicked *** when wound up.
BIG power resistors... or a variac... its a big problem though the power resistors shaving that much off I'm assuming you want to get closer to 400-450v B+????they are going to get hotter than living hell.....but can be placed on secondary B+ side only though....unlike a damn variac that drops everything heaters included because of straight into primary...and dropping too much will poison the cathodes....
For the tone stack to work on crunch ultra you need to remove/cut the jumper that link R11/C62 to the pin 5 of S1 relay.After that if you want to get a little more edge you can increase R11 to something like 220k because r11/c62 act like a fixed tone control. Removing them completely, I found out it leaves to much treble to my taste but is an option.For the speaker you can keep the same 8ohm an plug it in the 4 ohm jack to match/double the load on the output tubes
