But maybe indeed picking off the phone is the most dependable option here. Regarding the original thread: as I said I've managed to find KB2 schematics "somewhere" and could pass them on when asked for by PM.
So I tend to mess with a lot of equipment. I have "special needs" regarding phantom power (for instrument microphones I don't want to maintain batteries for) and hum resiliency (there's an overland power line starting in a transformer grid about 1/4 mi from here). I'll give it a try tomorrow and come back if I fail to get anywhere. Well, MS is running 7 hours behind my timezone which should be working in my favor unless I am running into someone with Monday morning blues. I can give them a call and get it for you. Yes, SMD has ushered in the day of "just replace the board." In 15 years, I'll only be able to fix tube amps, with big parts. So I am splitting tracks on a breadboard with a scalpel in order to solder that thing in, and my eyesight is not actually getting any better at my age. Right now I am doing a phantom power switch using matched P-channel MOSFETs and basically the only way you get something of that kind is an SMD chip. I am not actually interested in the truly recent stuff since it is both out of my paygrade and out of my area of expertise (and repairability also goes down with novelty). I'll try that, never mind the time zone differences and my accent. I think they are still trying to patent some of those circuits, and will hold on to them until the patents are granted. They will send you any schematic, except the truly recent stuff. I give them a call and they usually email me with a. It's astonishing what a difference in maintainability access to the schematics makes, so Peavey is to be lauded for being comparatively generous handing them to people who need them, even if the process ends up being a bit hit and miss sometimes. The KB2 schematics are somewhat related to the KB/A50 schematics I currently need (similar preamps and similar power biamp), but part identifiers are all different and so is the layout. I haven't figured out what would make the difference. I've had mixed success with asking Peavey customer service (the mail address) for schematics: sometimes I get an answer with the schematics (if I do, it tended to be about a week after asking), sometimes the mail appears to drop through the floor. Well, I found the KB2 schematic "somewhere on the Internet"™. It was taking multiple calls during the pandemic, but they should be catching up by now. You can call Peavey and get the schematic.
