 Its the same, the only different one is a el34 which I believe has to tie pin one and eight together. The kt66 and 6l6 are for all intents and purpose the same thing.

Ps: The jtm45 is really just a bassman, if you want to see if there are any changes, look for a tweed bassman schematic or layout as they used 6l6's.

Other than KT66 requiring more than 1.5 times the heater current of 6L6.

 Well yeah, there is that...  :smiley: Not a problem if he planned for 6l6's though...
