Cathode resistors

Post by crazy bill the eel killer »

Hello Dave,
Got the autoformer modules in house and want to get going.

Output stage is SE triode strapped EL84. Shared 100 ohm cathode resistor, possibly single 200 ohm for each channel. Bypassed, 200uf w/ shared 100 ohm, 100uf w/ single 200 ohm. Would prefer shared 100 ohm unless for your issues the single 200 ohm is better. Current is 90 ma through the shared 100 ohm, 45 ma through the single 200 ohm. I'll have some ventilation holes above the resistors on the top plate.

All of the technical issues ( capacitance, inductance, heat ) are above my understanding to assess. It just makes sense to me that copper wire will sound better than any resistor if it can be implemented.

Is it doable ? I'll trust your judgement.

Thanks, Crazy Bill

Hello Dave,
I'm guessing no reply means not a good idea and I should stick w/ standard resistors for this application ?

Thanks, Crazy Bill :?:

Hey,

I wouldn't say it is a bad idea, it is just an untested one. The few people who have used them in cathodes report great results but statistically speaking the sample size is not the largest :-)
