Re: Allen Wright style cascaded long tail pair?

Switzerland? Didn’t know you were in Europe, thats close!
Anyway, the data is at the bottom of the page and is written in both Cyrillic alphabet 6H6Π , and (N=H)6N6P.
I was thinking for about 480V biased at 25-30mA total, 50-100 Ohm at the cathodes and around 10-15K at the anodes, biased by a simple mosfet ccs. Only thing I do not know is at what point I got to bias the top triodes grids and also since Vkf is 400V do I have to lift the filament? Can you direct me a bit towards a more practical, hands-on suggestion-approach? As for 6080s and 6336s I got these 5euro each nos from a local military surplus dealer, I got about 5X 6336s and 12X 6080s. Thanks for the interest and help…...neighbour!
