Re: Memorymoog "DEAD OSC" on all voice cards OSC3

Hello, If you tune them by ear its a lot easier. Disable the auto tune (C-6) and enable only that voice (C-4) and tune it to a reference oscillator to start. Adjust the scale, but don't worry about retuning the initial frequency until you have at least a decent octave range set. Then test at 2 octav...

Re: Micromoog parts source needed

You really need to check the ground on the ribbon controller. If that's loose the ribbon won't work. However I can rebuild them if you need to. Send me a PM.

Re: Minimoog Squirrelly Keys!

I would check your cinch Jones keyboard connector. Those things can get squirrelly when you take them apart and put them back together if they're not clean.

Re: MG-1 won't play B, C and C#

Have you scoped out the top active divider yet?
The trigger for the mono section is generated from the poly section.
So if you have notes out on the TOC, the mono notes will not trigger.

Oscilloscope is your best friend for testing those.

Re: 1150 Ribbon Controller Slider replacement

Hello,
Your best bet is to repair the existing pot.
I do this all the time on vintage pots.
You will need to find the same make pot at any value, and open them up and replace the slider stem.

Hope that gives you some ideas.

Re: multimoog missing osc b pcb

Hello,
You might be missing more than the tandem board if you have open holes in the top of the unit.
There are 2 small circuit boards in the Multimoog.
One is the tandem board and the other is the (pot/switch) top board.

You will need them both.

Good luck on your search/project.

Re: Moog System 35 from Hell!!!!

Hello, I would try to isolate the issue first by removing the 921A and 921B (the most troublesome one) from the cabinet and putting it on your bench with another power supply and connectors. Based on the schematics, it only requires +12 -6 Gnd and then the summing node, reference ground and the PW i...

Re: MemoryMoog latest firmware for non-plus

Hello Memory Moog users, As much as I always like and learn from MC's input on things, I need to correct his info here. The auto tune update was designed to update the NON-Plus Memory Moog. The Memory Moog was release with version 1.4 and was installed on 3-2532 ROM chips. Shortly after that was ver...

Re: MG1 Part needed

Thanks for the reply's, I have tried a standard 100 ohm resistor, but the scale continues to change as the resistor can't adjust with the 3046 heat. As for sliders, This unit had the sliders replaced already. Rather poorly, I had 2 issues due to poor installation. I am pretty good at cleaning those,...

MG1 Part needed

Hello,
I am in need of the only un-obtainium part in the Moog MG1.
I am looking for a 100 ohm Tempco resistor.
One of them has gone out and the 1st oscillator will not stabilize.

Anyone have one, or know of a simple work around?

Thanks.
