Hi Guys
Note that PA66 can be operated with one or two power tubes, and can be expanded using PX66 to have yet more power tube positions. The tubes can be any type of the common pinout, as sets or as mixed types, and each biased or wired triode / pentode / ultralinear how the user wishes.
Remember there is absolutely no need for matched tubes, but the player can do as what pleases them to do.
The front end is optimised for 12AT7, which will provide the cleanest output. However, you can insert any 12A_7 for other tonalities and gains. A 12AX7 assists in giving a British tone.
