Leslie 122 Studiologic numa 2 connection

[Th'Rift]

Hey folks. I've been rocking the studiologic numa organ 2 for awhile now, I absolutely love it, but while the leslie sim is usable and quality, it's not my Leslie 122. Now, I know there's 1122 connection kits. I know there's the Trek ii combo preamp. But these things are beyond overpriced, and I live in Newfoundland, shipping things here is foolishness. It's just not an option. You can argue the economics of building and selling things in north America all you want, outside of labor it's about a hundred bucks in parts. 6 plus? Plus tax. Plus shipping. Overpriced. My only chance, aside from lucking into a trek from some Hammond angel, is to build something myself. I'm running into an issue though, where there are no schematics, no parts lists, no information at all really as to what's going on inside these things. So I come to the organ forum seeking schematics, information, or a new direction.

I've done some research but every lead sends me to a dead link. I found one super old file for a 147 combo preamp that was a mess.

Any information at all would be helpful, links, files, schematics, parts lists, pictures of the inside of a trek ii preamp, or all of the above for an 1122 kit. Or a new idea. Anything.

The only other option I can think of is reworking the leslie so the motors are powered from a wall outlet instead of my old Hammond and add in a Jack for the numa, external preamp if necessary, though I'd be much happier actually being able to play the Hammond through it as well...

Anywho, thanks for your time, any and all help is appreciated.

How handy/experienced are you with a soldering iron building electronic stuff with little parts?

[Th'Rift]

Rather handy, I have a knack.

With Trek II products, you get what you pay for. Don't write them off. The UC-1A is built to last.

I'm not sure what you mean when you say there's “no schematic” and “no parts list.” Are you referring to a schematic / parts list for the UC-1A, or the Leslie 122? You won't get a parts list from Trek II. However they are very generous about sending schematics out for people who are experiencing problems and need help with an existing Trek II product, but this is not one of those scenarios.

The parts cost for a UC-1A is a lot more than $100, I am sure.

Reach out to Booya Amplifiers in New Jersey. They can also build what you need. Boss Organ is another option. Both make fine preamp pedals.

I would avoid modifying the 122 amp / motor wiring if possible. It's not terribly hard to make a signal and speed switch that is compatible with the 122. You either pay for one that is already built, or you build it yourself. In a pinch you could emulate what the Leslie 8000 kit does. The most expensive individual part is the isolation transformer, sold by many companies including Tonewheel General.

Thanks muckelroy I'll look into all that for sure! I know the UC is a great unit, I don't mean to disparage the product. More so the economy.

Build a normal leslie connector kit (schems available online), and feed it with a small preamp (like the ART tube mp).
