Re: JX-3P doesn't boot up / power supply issues?
From where I'm sitting the 2w10 is a superior replacement to the original! As long as the polarity is right it should be fine. Was the original bridge rectifier actually defective? That's what I thought too...I wonder if the different spec (the "2" before it meaning 2A instead of 1.5A) is causing t...

Re: Prophet 600 vs Prophet '08
The P600 definitely has a ballsy sound that the P08 doesn't but then there's its greater functionality yadda yadda... Sometimes I find that I just can't click with a synth despite telling myself I really should. Sounds like it's that way with you and the P08. To be honest, that was my experience wit...

Re: JX-3P doesn't boot up / power supply issues?
Oh bollocks, it's never the easy option. Sorry for getting your hopes up. Could well be something shorted elsewhere... Have you checked the big electrolytics to make sure none are showing a dead short? You can try a simple diode test of the bridge rectifier but I find they're usually pretty rugged. ...

Re: Why a juno 60 ???
It's always nice to see someone using a vintage piece. Sure it would be cooler if it was a Prophet 5, Jupiter 8, OB8, etc. but a Juno 60 isn't bad. Anybody recognize the other keyboard she is playing? I think it's a good ol' microkorg. I don't think the juno-60 got any more attention than the other...

Re: JX-3P doesn't boot up / power supply issues?
Yeah it's a PSU issue then; all the digital stuff is entirely reliant on the 5V supply. The 5V & 7V supplies are separate from the +/15V supply and just uses a standard 7805 voltage regulator. Replace that and I reckon you''l be good.

Re: JX-3P doesn't boot up
In the manual it shows a few ways to check if the CPU, RAM and clock are functioning properly on power-up with an oscilloscope. Worth a try. Before that though check all the connectors. I had similar problem once and it was due to a faulty connection to the mother board.

Re: History of FM synthesis and digital synths
That was really interesting. I had obviously heard about John Chowning but I had assumed he was the life-long lab type. It's cool to hear how someone who came from a decidedly non-technological background could go on to have such impact in the world of science, even if composition remained his first...

Re: Shotgun Overhauls: OB-X
I have three scopes (including a modern digital scope) but in the short time I've had my signal tracer it has proven to be incredibly useful. I've added a BNC input so I can plug a modern scope probe into it to safely hear all sorts of things such as clock circuits, tracing audio paths, noisy pots,...

Re: Cheap As Chips
I saw that Godwin on ebay. To be fair it was a bit of a heap. Upon inspection inside the slider tops were there the masking tape residue made it look bad the panel otherwise is ok, no missing parts its now getting looked at if it cant be fixed will still have parts value stripped off. Fair do's. Co...

Re: Moog Sub 37
If I'm honest I'm not the biggest fan of modern Moog stuff but from the demonstrations I've seen I definitely like what I hear.
Not going to rush out and put my name on any waiting lists but I definitely wouldn't mind trying it sometime.
