I might have done something very stupid.... Brought a Fairlight CMI.

Sounds like you're about to have an adventure. Time to set fire to a Cohiba.

Haha! Don't think I can afford one now!

The 8 channel filter/vocodersque box sounds like a super cool idea!

We all have those moments, heh. A couple of nights ago I found something in the attic that I'd forgotten I still had - a Kawai SX-210! (8-voice poly, DCO/DEG, SSM2044 filters). Only trouble is, the CPU/DCO board is missing. Pretty sure that's how it ended up in the attic... Hmm. I wonder if I could...

Not Chinese, but I've used Lasermaster in the UK to have a replacement top case made for a Roland MKS-50. 0.7mm steel iirc, with 5 bends, various holes and slots and it cost about £45. I was surprised how cheap it was, but their pricing seems to be heavily weighted towards set up costs - two tiny po...

Not quite finished yet, but RE-303.

Thanks for the quick reply Devin! I've put it away for now, but will probe at the weekend and let you know what voltages I get.

Finally completed my Pro2021, but I've got a few problems. VCO1 is effectively an LFO: During calibration (adjusting TP120) the highest I can get for low C is around 4Hz. I'm assuming this is likely to be an incorrect resistor somewhere. More strangely, both VCOs drone all the time - the VCA seeming...

I've got two items in limbo at the moment. One from Japan that was sent over a month ago, with no further updates and another from Sweden that arrived in the UK three days after being posted and promptly disappeared into the ether. Last update was that it left Heathrow two weeks ago. That is the di...

A slightly toasty TC Electronic 2290. On first impression, it doesn't look as bad as expected.

Nice score...

1990s Soundcraft Spirit Studio 24 here. Absolutely indestructible, and although it has a single piece front panel, the channels are on individual PCBs. I brought it about 10 years ago for £200 iirc and the only thing Iv'e ever had fail was the power supply - which was just a cracked solder joint. Oc...

I've been reading a couple of articles on it. sanding it back to bare steel and having it powder coated might be another option for me, as I have a few other things I need coating.

No need to mask - this is a sub panel behind the actual face plate. Might follow your suggestion and paint it though. The newest IC date code I can find is from 1987, so it's taken 33 years to get this bad.

Having it replated is probably a bit extreme for me, though I might put some kapton tape over the metalwork to stop them coming loose/contacting the PCB.

I've currently got a TC Electronic 2290 in pieces to repair the power supply, but thought I'd use the opportunity to give it a good clean. On removing the outer front panel, I was greeted by this: IMG_20200728_134544.jpg I've seen tin whiskers on solder before, but these are zinc whiskers on the gal...

Cool I got mine about a week ago, but haven't had a chance to play with it. Perhaps this weekend...

I spent most of yesterday playing with it. You'll have fun at the weekend!

Hope you didn't pay shipping for the dead tranny. Nice score. Ha thanks! I feel ripped off. The dead tranny was not included. Instead I have a live one... The only dead thing I've found so far is the bridge rectifier. Somewhat intrigued about the melted wiring. Did the fuse get replaced with a nail...

This is seriously impressive! Very nice work.

The dead VCO had a short between two pins on the SMT transistor array. Now fixed.

Building a few more modules: Still have't got around to attempting the Tolex, but the first case is starting to look like a synth:

I bought a Roland SH-5 in semi-working condition and I just got it back from the shop!

There's something very special about '70s Roland. Need to get around to fixing my JP-4...

Finally, some modules! 3 702 VCOs built. Not calibrated yet, and I need to work out why one if them appears to be totally dead.
