Mission 75AS Schematic
Hi
Does anyone have or know of a schematic diagram for the amp on these subs. If I remember correctly the amp is a Cyrus built amp. Thanks Brent |

Ah, I was hoping that they would be similar to a couple of other bass amps that I do have schematics for, but unfortunately they are very different. Sorry.

Never mind cheers
Ive changed the caps on the various power rails and need to change the op amps for the gain , xover and phase. It uses fairly boggo TL074CN (quad) , a was thinking of using OPA4134 but thought id ask if there is an ideal subwoofer opamp. I could always use dual opamps and mount on a pcb to make them quad.

Unless you have something strange going on, then the OPA4227 is a pretty good quad to go with. I've used it in active crossovers before, and it works well.
