Well then best of luck with your repair. After all the work you've done to your psu, you deserve the right to succeed ! :)
Thanks!
I will have to recap my cs-70m's power supply (still working fortunately), because it's all original and it takes some time for it to warm-up (too long actually), and the volume pot is noisy when you turn it, but it's not a dirty pot because noise almost disappears when the synth is warmed-up.
Interesting - maybe it is some sort of oxidization that is temperature-dependent? Sounds like you should break out your scope and measure the power rails at that point ;-)
I want to install the kenton midi kit that I have for it, but will do once everything -or at least the psu- be properly recapped...
I had a look at that MIDI kit - looks like it will cost me around AUD$600 to buy, which is a lot, especially factoring in that I have a whole pile of gear I'd ideally like to get converter kits for. I'd be interested in hearing what others who have one installed have to say (or if anyone has one they'd like to sell me for less than that much.)
You just don't want to open those beasties to often ;)
In general I agree, but I have to say the CS-70m power supply has been pretty convenient to work on. The leads from the transformer are long enough that I've been able to leave it connected to the "DC" board with that board sitting outside the case, nice! I'm not so impressed with the exposed incoming AC supply lines on the rear panel switch PCB though, best keep fingers away from there :-\
Cheers,
