Hi, in this transmitter, two 220v to 6v transformers are used back to back to feed the 12au7 filaments on parallel mode (6.3v) and also HV for it's anodes.
I wonder, shall I ground (connect to chassis ground) one end of the 6v side of the transformers (i.e. the pin9 of the 12au7) or shall I leave it floating (balanced)?
Which is the best way to do it?
