[Lukaamp]

Hi, can I replace cathode resistor of 130 R 1W with some other value (100R, 150R, 180R ..etc )? And if I can what it heppens?

Thx.

100ohm --> more plate current, tube runs hotter, may be too hot
150ohm --> less current, tube runs cooler, less output
you can however connect two 270ohm resistors in parallel, that gives you 135ohms, close enough ...
