Thanks Kevin but I already have these- I received a printed manual with the Quadra which is 2461-2463 models, however the schematics included are still the 2460. Perhaps this means they only published these schems...

Guess I'll just work it out through trial and error.

Cheers

Hi all,

I was trying to verify the function of my membrane, but I couldn't work out why my interconnect diagram didn't seem to match up to the synth... I have a hard copy manual which came with the synth, however the schematics are for a 2460 version while my synth is a 2461.

Does anyone know if ...

Hmmm yeah thats certainly what things are pointing too... I might just have to buy one and swap them out to see for sure.

In the meantime I will have another poke around to see if I come up with anything.

Thanks again.

Hey,

Yeah that all seems pretty spot on. The maths is where I fall short also! I may try to get an engineer friend of mine to check the schematic and see what he thinks, don't wanna take up too much of Kevin's time, he's also helping me with my Arp Quadra I recently acquried!!

I have the 1V p-p ...

Thanks so much for the info guys.

Kevin, thanks for your input. Particularly as I was getting ready to order something like the 100 or so logic chips in this unit!

As I said there are a few membrane switches out, however it changes programs ok, the LED's turn on and off, and the lead section ...

IT is possible that someone went wrong with the PSU and fried them- I don't know the history of the unit.

Have checked the outputs of those transistors, no signal present there. Only millivolts of noise I would say.

I will double check the 14.5V around the board, though I'm pretty sure its present ...

Hi all,

I have a Moog Opus 3 which I am trying to repair. The main problem is I am getting nothing from the Chorus section at all.

I can verify that both the actual generators in the Chorus section are working- ie both the direct Organ and Saw string via the eq are functioning. Right after the ...

A very interesting read indeed... especially as I am about to begin a Quadra restoration of my own!!!

Mine has many issues- only the lead section works and is the arpeggiator is stuck on, couple of keys don't work, and a couple of the membrane switches don't work.

For this reason I am considering ...
