Try A Screen Driven Driver Stage Article By Rikard Berglund From Sound Practices Issue 8, Winter 1994/1995 Some output tubes (211 and 845) need a very high drive voltage with low distortion. Some tube freaks have used the 300B tube as a driver but it is very expensive. Others have tried to use a triode connected EL34 but it is not linear enough.

I had an amplifier called a Delcon T210. It was made by HP for the airforce and used in mars stations. It ran 3 x 4cx250R tubes. The PS was seperate. It was extreme quality with dual vac caps and silver tank. The PS had hypersil iron all around. This amp ran 1500 watts out easy. Current was about an amp and I think the HV was 2600.

Screen drive pulls the screen grid up toward B+ at the same time the plate voltage is near zero causing a large screen current at the peak of the sine wave. This would not be a problem with music since the average power is far lower than the peak, but it can lead to fireworks when the amp is operated at 150 watts in clipping for about 2 minutes!
