Muzzle 4301 RETROFIT PCB NE5532?

[Moltenmetalburn]

I just had one of these arrive but dissapointed it has 5532 soldered onto it? I planned other opamps.

Is this how they ship, or is mine an error? I didn’t notice anything anywhere about them being added. just my mistake?

Thanks!

Are you saying an NE5532 is soldered to this?

Yes. Amended my title. Thanks.

Okay. I think it's always been setup as a THAT4305 with the NE5532s, but @Robert can confirm.

Yes, of course, it's a drop-in replacement for the THAT4301, no assembly required other than your choice of pin headers.

I do have some of the unpopulated PCBs if you want to go that route, but you'll have to install your own THAT4305 and passives as well.

Ok thanks, everyone.

Well I popped this thing into a few working builds and now they dont work properly.

Pins are correct. Pcb was cleaned and tested. Its the same problem everyone has mentioned.

You cant set the gate high enough to use it. It kills ALL the signal if you do. Set it low
Enough to have signal and ALL the noise is passing.

Ive had zuul and clones since batch one of both, not user error. Built yet a third full muzzle classic to see and same thing.
