Tubes are voltage amplifier,silicon devices are current amplifiers' if you are music connecer you use tube based class a amplifier. Also tubes are mach faster in low frequency responce.

Hi all,

can anybody tell me  in what context electron tubes are faster that silicone devices?
comster,nice drawing....short pulses.

Switching speed.

Vacuum tubes have relatively low (compared to most silicone) interelectrode capacitances.

Propagation delay is whatever the time speed of light takes to travel from cathode to anode.

@ comster
see your design.
1. unusal design shematics ,
2, Outup stage Transitor nust be PNP Transitors.
Give Attention to Polatiy of Supply and the Diodes
(spezially thatone that got to Emitter from Tr.

@ all
tubes aremore sensitve in receiver diagrammes, because
input is very high ohm impedance.
Microwave tubes exist before 2. War , and cannot even
replaced (anytime) with Transistors.

@Pese
Thanks for the input.  I'm no pro, just a hobbyist. My intention is to try to build Tesla's rotating ac wave using a dc input as simple as I can. A great learning experience to understand resonance and frequency.
