Hi All

As you know from Scott's thread, I am building a integrated line stage/phono preamp for him using 6N1P tubes. I am following the audio section of this schematic:

I am using a R-core voltage doubling power supply and I want to see if I can get away with AC on the filaments and CRC regulation.

All is well, except the plate load resistors for the triodes need to be recalculated.
