AO44 questions

Post by lovecoffee01 »

I've acquired a m102 organ with an ao29 and ao44 chassis. I also have a ao43 chassis that I'm planning on doing sluckey's plexi6v6 build with but need to wait for some funding. The ao44 chassis seems like a pretty good candidate for a fairly already complete build that I need few parts to complete. I'm completely new at this but have been lurking for quite a while. I'm thinking of turning it into the sluckey peewee but would like a bit higher gain of an amp than the ab763. I'm thinking of pasting the preamp from a trainwreck express onto the input of the phase inverter and adding a presence control to the cathode of the third cathode. Would the preamp work with existing voltages or would they have to be tweaked? Anything else I need to consider? Would my presence control work? I know for all the pots etc. I'd need to use a different chassis. Thanks in advance.

If you simply move the feedback tap off of the Pee wee to the 4 ohm tap you will 30% more gain until that global feedback voltage runs out.
That might just be enough for your needs, or you can just open that circuit altogether.

Ok, then drop that 100k resistor feeding then presence pot down to about 70k and the effect will be the same.

Okay I'll try playing with values.
