Hi,
i'm trying to design an AM radio based on a ECC86 design, but with other tube, because this tubes are very rare and expensive...
My main doubt resides in the triode plate voltage. The datasheet of any tube gives a voltage on the plate and I don't know very well what to take of it.
Ex. If the triode plate voltage is 250+ Volts, what does this means ? The maximum voltage that can be handled by the tube ? The minimum voltage ? The main voltage, meaning that it must be no more no less than 250+ volts ?
Cheers.
