Hi,

Thanks in advance

Ps.Excuse my bad English !!

Not a cathodyne, but this ECF80 splitter works well.😉

hey, the ecf80 is a nice tube, my heathkit s-33 uses them as preamp tubes and it's a lovely sounding amp. i know this isnt really helpfull but still.. 🙂

The o/p tranny 6550 g2 resistors look way high at 2K2 3W components ? eh....or have I misread it at 220 ohms which would be more inline ?
