I have a vague memory that one of the valve/tube manufacturers suggests limiting discharge current to 40-50A for 'normal' tubes, which would imply a higher resistance. Can anyone confirm/correct plea

Ameritron has about the simplest circuit around. They make a 120 volt and a 240 volt model that work outboard of the amp, or the parts can be installed inside if you have room. I have the schematic s

Isn't the idea of a glitch resistor to act as a fuse ? Don't you want it to open on a glitch? Absolutely not! The purpose of the glitch resistor is to limit the energy (joules) that is stored in the

It can do 2250 + watts. For how long depends upon the mode. The weakest area in this amp is the tank circuit. Several RTTY operators have reported a melt-down of the tank coil on the low bands, due
