Hello, I'm building a Minimoog and 2 parts I can't find. It's the E101 and E112 transistor. Does one of you have these parts for sale, know were I can buy them or knows a alternate part please let me ...

Does anyone have a decent copy of the OBXa factory patches as an audio file? The one that is floating around the web is useless as it doesn't have enough leader tone.

If they are the same as OBXa knobs I may have some, do you know if they match? I would need to do a garage search though, might take a few days.

The popping and clicks are the symptom that comes from the bad caps, but it seems you have another problem in there as well. Most likely a bad chip, you might as well replace the 2 filter chips, and i ...

What are you hearing now when you say that the synth section is now louder? Didn't you say that it was dead except for a click? What are you hearing from it now?

They're the ones. Worth trying replacing them before you try anything else, shouldn't cost you more than 50P.

BTW, when you pull the centre panel board to work on it, when you finally re-assemble it just check the solder joints on the wires that run to the PCB's on either side, they are easy to break.

It is a waste of time troubleshooting this machine with a multimeter, you need to get your CRO going or at least build a capacitively de-coupled audio probe. Have a look on the switch poles of the LP ...

Hi Matia, sent you my Paypal address via P.M. to keep spam down.

It's Saturday here, so I can post it on Monday morning, (Sunday afternoon California time).

All the best, Steve Jones.

Post would be $4.00 for regular airmail. I have 39 left.

I have a half dozen used ones (some on a Rev2 Prophet 5 voice board that is in my workshop), but I have no idea as to whether any of them are faulty or not, I have been waiting for a Rev 2 to come in ...

I have plenty of NOS CEM3372's. $28.00 US each, plus postage.

It is probably something that you would just have to try and see, I have never heard of anyone doing it, but it would be nice if it worked!

If you have a multimeter or oscilloscope you could then look and see if there is a CV and gate coming out if the E.S.P.

Have you turned up the VCO modulation knobs so that the control voltage can get into the VCO's? The VCO CV jacks don't work without the pots being up.

Yes but Seraph, The theremin is the ultimate multi-temperament microtonal instrument. I think you should take up the Theremin. Very Happy

Thank you for all that info, I will start looking tonight.

As a service tech I used to build small Theremins for fun, and I am hoping to get a Moog soon. I heard a documentary on the ABC about 2 years ago, and I have forgotten the players mentioned, but some ...

Hi there, I only have a schematic for the pedal unit, which contains the pre-amp only, not for the main Hi-Fli unit itself.

I don't generally supply copies of schematics except to other service techs that I know well, but if you have problems with your OscAR I will be happy to direct you around the circuit until you find a ...
