T-series chop

[49bv]

I was thinking about purchasing this T series chop. I wanted to get some expertise to see if it would be worth it. I hear that they are solid state. So what would the situation with the preamp be?

[tpappano]

Does it have any electronics at all in it?

[49bv]

The percussion and vibrato were removed but I'm fine with that for the sake of portability. But I'm trying to find a t-series service manual to look at what should still be in there. I don't see a pre amp however. And I'm guessing that run capacitor hasn't been changed.

[tpappano]

Do you see a 1/4" jack anywhere on it? My guess would be that's what they did, then patch the thing into a guitar amp, or something. I repaired a little Marshall amp for a client recently and to try it out I connected it directly to the matching transformer of my CV. Sounded pretty good! The T organs have a *bunch* of circuit boards all wired together with the tab switches, etc. If you don't see anything like that in the chop, I'll bet they were just coming off the transformer.

Depending on price, that's a great chop. Built a couple very much like that in my day.
Yes, it'll have a 1/4 out somewhere on it. Not real hard to do if it doesn't.

Then you can grab any combination of guitar pedals you want. Tube preamp? Sure. Or any other distortion you like. Phasers, flangers, and especially chorus. Build a pedal board and away you go. Notta fully functioning Hammond, but you knew that going in.

Hi, it looks a tad short on drawbars, is it single manual?
From what I see in the box, it very much looks like a passive build that takes instrument level off the MT and into a DI as a preamp somewhere. And, as ToG mentioned, it is ripe for adding pedals and whatever subsequent amplification you fancy.

Also, swap that Run Capacitor as soon as you can
a) it is probably crapped out and
b) it is full of nasties if it pops !

And the generator is fitted backwards (!)

Just noticed something else: it might be a T-series generator, but it has the matching transformer and drawbars from an M-100. Wonder where the manual comes from?

[49bv]

Thanks for the help y'all. He said that it comes with a matching transformer and capacitor start. There is a 1/4 inch coming out the front. Yes it is only one manual and I will change the run cap as soon as I get it. Is it a problem that the generator is backwards?

[tpappano]

Should be fine. There is a possibility the matching transformer could pick up hum from being near the motor, but you could move the transformer to the other end If needed.

[Papus]

Should have tons of key click and growl like a beast since there's no extraneous circuitry to dull the sound coming straight off the matching transformer.
It appears to have the bare mimimum components required to generate the tones, mix them via drawbars and output via transformer.

Play it through a Marshall stack.
Job. Done. Instant Jon Lord.

Replace the motor run cap immediately - it's a time bomb
