Good. I don´t think Moog would design something that relied solely on what tantalums win over electrolytics but space saving. That said, I wonder if lower ESR would make my Rogue´s attack faster than 4ml sec (edit).

From what I´ve read, subbing old tantalums is almost obligatory. Never saw electrolytics used as oscillator timing caps, or tantalums for that matter. Think you´ll find polyesters there, because the capacitances are very low and they´re not as sensitive to changes in temperature as ceramics. In the ...

The volume in the 106 is a stereo 10k logarithmic. Check the pot´s dimensions and if it´s to be soldered on the PCB or wired.

The reason tantalums are used is higher capacitance on a smaller footprint. I don´t know if modern ones are better, but some vintage ones short when they go wrong. I´d use electrolytics instead. Some capacitance values are not critical. Best thing to do if you don´t want to wait IMO is to look in th...

Good news then. Poly caps are robust. Although I´ve never seen that happen before, common sense tells there´s nothing wrong with them, it´s just the paint coming off. Anyway I have a capacitance meter so I´d of course check the values of one or two just for piece of mind... The tuning problems and t...

As far as the wire acting as a current limiter, it could fail if the current is more than the wire will allow. I have had it happen a few times on small boards I made for our in-house equipment. I went to a larger gauge wire and the problem was solved.The few times that it happened, the failure was...

BTW fixing those traces should be your first priority.

I see. Well I never saw anything like that before.

What comes to mind is a continuity test and to protect the traces with a good insulator for PCBs before it gets worse. Kontakt Plastik 70 is good. Let´s see what techs have to say.

There is some confusion with the best way to clean circuit boards, when I was doing work on my Roland CR-8000, I did most of the work with a toothbrush and a bottle of decent methylated spirits - this is what an old electronics guy recommended to me. If it's still dirty after that, just give it a q...

Download the service manual here: http://www.univox.org/moog/ Judging by the 1 Watt resistors and the Wima caps that synth has been serviced/modded before.

The only useful mod I heard about is the vcf upgrade for better low-end response. It´s only a cap swap.

The oscillators track well and stay in tune, that´s a good sign. Did you try the 901a too? Would love to hear a comparision. also, as you can see, I haven't figured out the gate/trig yet, but I'm working on it From the picture it seems the gate/trig are hardwired and are selected at the module to th...

Lucky you. There´s a demo of the Moog Modular V @ http://www.arturia.com/evolution/en/dow ... demos.html. You could try and replicate the patches.

I guess this thread sounds a bit silly without some pictures of the actual board. I´ll post some when I get my cam back.

BTW, the original regulators were 78M12 & 79M12. Will these act as current limiters if the circuitry demands for more than they withstand, or fry?

Thank you it's cleared up the mystery....Now i have to get it working as the filter does not work and the output is very low...The osc are fine ...? YW. Well, now you´ve got the schematics. If you decide to fix it yourself I´d like read about it. That filter is 12 dB and multimode. Resembles the Ob...
