<I think it´s getting abouth time to try a DAF-amp myself, have a lot
<of QBL tubes collecting dust in the basement.
<73, Jim SM2EKM
<Ps: How about 4-1000A in a G2DAF amp, would that tube work?
Jim,
My belive is that it should work just fine. I know that 4-400 has been used in
DAF amps, and 4-1000A
seems to consume about the same maximum screen power as the QBL5/3500. g2
voltage is rated 500 to 1000 Volts depending on the class of operation wich is
fairly simple to achieve with a diode quadrupler.
Max Screen dissipation is 75 W and max Grid dissipation is 25 W. That should
indicate that 100 W of
drive is enough to drive the tube to its limits.....
