gl...remember, if you use the Hammond P-T 124E as a dirver trany,
and either PP or Parallel 12AU7, you must "back" connect it...

Steve - what exactly do you mean by "back connect" it? Reverse the primary and secondary connections? I have seen mention somewhere of this and using a resistive divider on the "New" secondary to apply grid bias.
What is the reason for "back" connecting?
