PY 81 as power rectifiers?

[Amie]

OK. But you still could.

Transformer winding to chassis. PY81 heater between chassis and 15V tap. Lights the heater OK.

Transformer 230V terminal to PY81 anode; cathode to reservoir capacitor and HT+.

Yes? :-)

(I applaud your wish to use the PY81 rather than silicon, after all, REAL amplifiers and radios do glow in the dark!)

Overload the transformer 15volt section when current is drawn from HT? I will draw it out when I'm home and see if its obvious where I'm wrong....

Amie.
