Re: And the next one! a GEC BT2147
Great performers. The only let down is the GEC triode tube that tends to go O/C, low resistance heater and low emission. You probably have one of the good ones!
The B36 is the line and frame oscillator. It can be replaced by a 12SN7GT. I have a few spare B36's if you would like one.
The sound output valve is the little N37. John.
