I plan to use the best oil caps and Lundahl LL1668 plate choke, or consider to eliminate the caps with Lundahl LL1671 combined plate choke/interstage trafo.
Grid chokes in both stages and driver filament filters C-L-C .
All monobloc SEDHT amps I've made are quiet on Avantgarde Duo (107dB) with shorted inputs.
Are the Ca or 3A/110B tubes capable drivers for DET5?
Thanks, Johnny.
