Guys, i have built 2A3-6SN7 based, where my operating point is 350V/55mA on 2A3 Plate and cascode 6Sn7 with resistor load. both of the work at 4,5 mA. I

but right now i want something better than this. I'd like to try some 2A3 DRD design, can someone suggest which design should try. I don't want Electra print 2A3 because the driver tube is quite rare in my country.

thanks
