The amplifier is designed around the ECL82 tube, which includes both a triode ... posted up detailed build instructions yet, his simple schematic should be all you need to get started.

[Mikremk] demonstrates this with a simple but effective amplifier using a PCL82 triode-pentode. It’s a conventional tube amplifier circuit in which the triode is a preamplifier for the pentode ...

The schematic shows one channel of a stereo amplifier, and the power supply is sufficient for both channels. Transformer T2 supplies the voltages required for the vacuum tube plates. Selection of the ...

LTspice simulation of the K2-W Vacuum Tube Op Amp’s design reveals ... current for our classical diff-pair amplifier on the right half of the schematic (the loads on both diff-pair halves ...

LTSPICE schematic of the K2-W Analog Computer ... in current between the cathode and anode, and an amplifier is born. So, think of a triode tube as a very-high-voltage FET that gets progressively ...

As one can see, the second harmonic of a 5 to 15 W tube amplifier dominates the spectrum, and EL34 type lamps are used in the output stage. Note: Expert opinion and a US patent are useful links on the ...

That we have something for every budget is also a testament to the health of the tube amplifier as a concept. It suggests that players of all ages and levels are inspired by the idea and that ...
