A question before anything: do you feed the 7788 DC or AC on the filament?
Many tubes are perfectly able to oscillate mechanically on 1KHz--20KHz range, ...

Hello Romy,
Quite clearly, a high Gm device will have a higher voltage gain than a lower Gm (for pentodes, gain is Gm*Rload if single ended) and this is something we are after in a MC stage. Noise performance is crucial and below I am analyzing a ...

I have tried a number of high Gm pentode/triode tubes, including E55L and, of course, 7788. All are very linear when used as triodes, but do not bet on very low noise, if that is what you would be after. Th...
