Hey Joe or anyone else,

I'm curious about the mid eq mods on the PM2000. I have some that I bought from you a long time ago and they sound great.
Now, I'm doing some upgrading of the IC chips in the PM2000.

My question is: I'm pretty sure that the mid eq mods don't bypass IC8 and IC9 right? I can't figure out exactly where in the schematic the JLM board is being inserted.

If it did bypass IC 8 and 9 that would be really great because that would be two chips less per channel to replace, but anyway, I uploaded that part of the schematic for convenience.

IC 8 & IC 9 are bypassed when our PM2000 Passive EQ kits are fitted so they can be removed if you want.

See our PM opamp adaptor kit for upgrading old TA7322P & HA1457 SIL opamps
