4- 300z tube box

how much drive? and max pep you should see???? what would be a good driver for this amp?


Max drive for linear output (non tuned input) is about 600 watts, pep.

Tuned input, you need about 450.

Output is dependant on plate voltage, and how much current the transformer can take. But, you can figure about 900 watts PEP of linear output per tube.

If it's biased deep (as most are) then you can change those PEP numbers to "bird watts". PEP won't be much higher.

    Hello gentlemen and Ladies. I have the dreaded RCI-2990 receive issue where my radio gets distorted when people get close to my location. I found the C90 Capacitor, but I can not for the life of me find the C89 capacitor. Can or does anyone have a picture of the exact location of C89 ? Thank you in advance, Wes
