Thank you very much :Tamas, Gyraf, CJ, Samuel Groner, and everyone else....
This passive eq is based on the Pultec like circuit.
No pots- attenuators only.
Everything hand matched- tolerance limitied by DMM but <1%.
12 tap inductors, >1% tolerance, ch. to ch.
Stancor 4:1 into Big Bloak
into filter network into Big Bloak into
Stancor 1:1 or Iskra 1:1 output transformers (switchable by relay).
-6 /+ 9dB(u) gain regulation.
All controls 12 position MBB rotary switches (Lorllin)...
work in progress:
I LOVE IT :green:
