Re: Kees Talen's "space charge" regen

Bernd, excellent point about the TPTG, which i had not noticed. A triode tube with resonant circuits in both grid and plate circuits. That is asking for

Re: Kees Talen's "space charge" regen

While simulating the circuit, it broke into oscillation. it behaves like a TPTG oscillator. No wonder, to grid and plate are equal coils connected with similar

Re: Kees Talen's "space charge" regen

Here is my question. We can, and in fact did, read the designer's "bullet points". As an EE, what do you say about this 'bullet point' explanation ? What would

The B+ voltage is 160 volts. That is possible without a power transformer in the power supply. Because 117 volts RMS is 160 volts peak to peak, and therefore
