PPG Wave 2.2 / 2.3 Rack PROJECT

I have a significant amount of time [both mine and others] and money invested in making this work.
I am at my limits of abilities to work on it. I can get a display to run but no sound because of the Proz-mismatch.
The problem with this project is that there were never the appropriate board combinations to make it work. The minor repairs aside, it will never make sound with what I have here. A PPG 2.3 processor board is required to make the voice cards work with this configuration. Alternately, you could look for PPG 2.2 voice cards and a motherboard. Unfortunately the market for PPG synths is very dry in New York, there are far more users, techs, and parts available in Germany in Austria. Interested parties, I recommend you consult with Alexander of Virtual Music in Vienna, Austria about sourcing another 2.3 processor board to make this configuration work.
The PPG has the latest Virtual Music 8.3 ROMs. I am including a second set of ROMs as well.

When this was shipped, the cards were not removed and wrapped so the damages are listed below.
• 2-3 broken mylar caps [the leads are hairline thin and very fragile]
• 1 broken 27.460mhz Crystal
• LCD cable pins are bent / broken and some will need replacement.

"Details from the original listing[s]:We don’t know much about this. What we do know is it doesn’t work. It would appear that someone took a PPG Wave 2.3, removed the PCB’s, display, knobs and power supply and re-mounted them in a rack-style case. The front panel has a very professional looking blue and white transfer so whoever did this was quite serious about it. It also comes with the Wave’s original Mod Wheel assembly which can be connected to the internal motherboard. We tested it and this is what we found: It appears to boot up and display what looks like sensible information on the LCD (see photo). It accepts commands from the front panel, such as program or Midi channel changes, or for example pressing the Analog button brings up the current front panel knob-settings in the display and these can be altered in real time. It also appears to have valid data in memory judging by the parameters when the program number is changed. It can also be switched to emulate PPG Wave 2.2 mode. So far, so good. Now the bad news: plugging in a Midi keyboard produces no output, so either the Midi circuitry or the sound-generating section has a problem. Without having another Wave to test it with against, that’s as much as we know. Ideally this would suit a PPG enthusiast who has a working Wave 2.3 and can diagnose this one using an external Wave keyboard and card substitution.

Here’s an interesting one. Possibly the world's only rackmount Wave 2.3. This was sold a few years ago at VEMIA not working, but has now been serviced by James Walker and is fully operational. *Just to confirm: this has MIDI!* The keyboard was never the best thing about the Waves anyway, so this might be ideal for someone who wants the sound without the space. We have no idea who did this in the first place, but it looks extremely well done. 

This mystery PPG Wave was modified allegedly in Germany. It was purchased as a non working unit a while ago but as yet I haven't found someone conversant enough with PPG's to get it 100% working. In the interim period I bought another Wave, so the project's been on the back burner for some time and is now surplus to requirements. I've recently had synth tech Kent Spong take a look at it, his professional opinion is.... 'It's not an impossible job but it will take an expert in PPG's.' For the record the case isn't 19 inch rack size, being slightly wider at 19.5 inches wide, either way it's definitely more compact than the standard Wave. Last time I looked the unit powered up and the front panel display reacts normally to edit data from the knobs, however it's very intermittent in it's behavior and hasn't made any musical sounds as yet. A potential bargain for someone willing to do some research and hopefully nurse it back to full health, or perhaps a source of rare spare parts."
