Bob, these are the questions for you.
1) I don't see the power transformer from this picture (see link).
2) I know your new driver on M-70 is 6SN7 tube with tube CCS. However, I want to use 6FQ7 but the chassis layout for octal and has an extra hole for the CCS tube mounting.
Do you have M70 made for "old" driver board with 12AU7? So I can plug in the 6FQ7 without one extra hoke for CCS and 2 big holes supposed made for octal?
3) Can I order the M-70 without the driver section? I can hardwired this section with my own MOSFET CCS with 6FQ7.
4) The output tube on M-70 is EL34, right?
