Okay guys, got replacement parts, but the PCB had lost some contacts, did anybody can give me a close up photo of the area above RV23 please! (if somebody saw a "blank" pcb, this is helpful. I made those photos, maybe somebody can help me with it.

On the first photo, i need to know the middle and left pins


On the second one, the middle pins.

Greetings. We have had one of these for about a decade that came pre built from someone, no idea who or what. They used good parts, though, and it has the little DIY EL panel rather than a vactrol or something.

I recently hooked it up and started using it regularly after unsuccessfully trying to sell it for a while.

I calibrated it and it is behaving just fine, but I will say from experience recording and mixing with real vintage LA-3A’s (and even the UA plugins…), this one just doesn’t have the same kind of “vibe” to it. It sounds good, just a little slow and sort of “boring” if anything.

Sifted through this big thread but wondering if there were any circuit fixes / improvements made to this project back in the day.

Again, I don’t think there is necessarily anything functionally wrong with the unit. It just doesn’t sound as good as other LA3A’s!
