Please offer any suggestions for installing a new triode in a Henry amplifier.
I've purchased a NEW Eimac 3CX1200D7 (YU121) from Richardson Electronics as I wanted a spare for my Henry Ultra amplifier. The amplifier is running well with its original (1991) Eimac 3CX1200D7 in place, so I want to remove that one and place the new one in service to ensure its working well and to determine output.
What is the best way to start up a new ceramic triode? My plan was to install the tube and turn on the amp and let it idle for 4 hours before applying any RF to it. The 3CX1200D7 is an instant on tube that will have 3600/4600V plate voltage and 6.3V on the filament.
Suggestions?
