Any Waldorf Wave techs here?

Working on a Waldorf Wave synthesizer. It has not been used for a while, and it just had all its panels rescreened. The unit boots, but fails with a fatal error' cant find audio card ' or somesuch. Runs various test routines OK.

Hmm, crickets! Just to give some follow up. This unit has a processor card that plugs into a bus with two DIN 41612 96 pin connectors. One connector showed some corrosion, so this got me looking at it. Turns out that on pins 6 to 10 in all three rows, it was not making contact, plug through socket.
Sigh! So I took my time removing the connector. Another board where the designer used too small a hole size! But I cut all the pins one layer at a time, and I think I have got it out without too much damage. Now i need to wait for a connector to turn up, and I can see if I have fixed it, or if it needs more work. That work will be ugly. I did try to contact Waldorf, but no joy from them. And I beleive one of the Waldorf designers and gurus recently died.

The Waldorf company that built the now-legendary synths like Wave, Wave II, Pulse, Attack, Q, MicroQ, Access Virus A, B & TI filed for bankruptcy, I think, quite some time ago. The follow-up 'Waldorf' that made the Bloefeld was not really the same company. No support for old series synths even back then. Today's Waldorf looks like yet another thing...

Any success so far with your Wave?

I was manager of the importer of Waldorf, Acces, Kurzweil PPG etc. from 2002 thru 2013, ran the retail store as well and also serviced the gear, new and earlier models. Reseating and cleaning all edge connectors, cable connectors and reseating any socketed chips is sort of par for the course with these - I serviced one of these a couple of years back along with 2 PPG’s and there were so many dodgy connections throughout all of these machines plus a failed board in one of the PPG’s which I managed to get a new board for.
The Wave output board with all the audio out summing IC’s needs to be tested to ensure all rail voltages are present and it is passing audio. They use a lot of SSM 2132’s which are an upgrade/replacement for the 5532 and also use a lot of 4558s and TL0xx’s. Not sure exactly where the check line is on the output board - would need to look at the schematics again which I do have if you’re still having problems.
