Beautiful setup. Please provide porn details on the crossovers and amps.

well ... xover. I am using a Beringher CX2310 to drive a VT52 differential amp (IT transformer, tamuras) and a 801A spud amp. Midbass and mid/high crossed with 6dB/oct, so just a cap, inductor and a handful of resistors to attenuate 3dB the 4001
Hello gluca
Do you find the 801a spud (single gain stage? or with input step up transformer?) to have enough gain for the horns?
I like the 393As' glow, beautiful. Are you using the grids as plate? Can you share a schematic of your PS/amp?
Thanks,
David
Hi David
Yes, grid as plate. PSU is a mixed bridge (393A + Schottky diodes) into a LC filter followed by a CCS + C. Final voltage is 500V, the tube will set its plate voltage and the CCS is dropping 20V or so.
Gapped 16k output transformer and zeners under the 801A. Input step-up transformers removed but a (big) 1:4 or 1:8 would work there.
I am using LC filter + Rod Coleman's regulators to heat the 80A's. Amp is dead quite.
I googled but I could not find an updated schematic, sorry.
