[sdiy] More thoughts on GlassFET ladder filters

[John L Marshall]

I think that 6AL5s would work well. Your heater isolation issues go away.
The forward drop is low at around 10 volts.

If you need additional information I have manuals from, Sylvania, GE and RCA
as well as the Radiotron Designer.

Take care,
John
