radardoug said:In a standard Pultec there is an input transformer, then the eq network, then another transformer. So there is NO d.c. in the eq section. If you put one of your aerovox caps from the plate to a 1M, and get 300mV of d.c. across the 1M, the cap is leaky.
Buy a new cap.
radardoug said:Is your interstage transformer wired correctly? Sounds like you might have the windings connected wrong. The primary should be grounded one end, and go to the output of the eq at the other end. The secondary goes to the 12au7 grids.
