Note the Cynthia panels below. Via the listing: "This is kind of a round-about story so please bear with me. Several years ago we purchased a wing for our ARP 2500 synthesizer. Although all of the modules worked, the wood casing was badly damaged. So we got the brilliant idea to remove the modules and convert them to rack mount (standard 19"). There begins our tale of woe. We contracted with a well-known Los Angeles synthesizer module manufacturer to undertake the project and paid a large sum of money as an advance. This company did a superb job of designing the front rack plate (picture 3) and the metal shop that fabricated them did a superb job, too. Several years later, though, the project was bogged down, nothing was happening. In fact we had to pay the metal shop directly in order to get the plates, then we had to retrieve the modules, etc.
We thereupon contracted with another well-known Los Angeles synthesizer module manufacturer to undertake the project and paid a large sum of money as an advance. A year later nothing had happened, in fact it proved difficult to retrieve the modules and the metal plates. At this point we no longer have psychological stamina to complete this project so we are offering it to somebody who can. Here's what you get. There are two complete, fully-engraved panels with all appropriate mounting holes (picture 3). You will need to supply all of the jacks (you will need 240 of them to fully populate both of the drilled racks). There are three panels that are engraved but that do not have holes (picture 6, sorry about the flash glare). We will give you the name of the metal shop that made these and it will not be costly to get them drilled should you want to. Our concept was to ditch the sliders, which were somewhat beat up (and as anybody who has used this synth knows, are not particularly intuitive to begin with). All connections are to be made directly to the modules via jacks that mount on the panel. Notwithstanding we are including the sliders, two of the "large" type and two of the "small" type (pictures 4 & 5). They do not have the little plastic colored slider caps, the wires are entangled and it would take a lot of work to restore them to full functionality, which is why we recommend you do not try to repurpose them for this installation. There are five edge card sockets, you will need to source two more however we understand they are not difficult to find. There are six modules (pictures 1 and 2): 1033 dual envelope generator; 1023 dual oscillator; 1005 mod amp (missing two switch covers); 1004-T oscillator; 1006 filter amp (missing a switch); and 1027 clocked sequential controller (missing two switch covers). Like I said all of the modules were working when pulled from the original damaged wood cabinet, however, we are selling them as is. They are clean with no missing or broken parts except as noted, evidence of electrical fire, etc. Cosmetically the modules are in G+ condition as depicted with some light scratching, nothing untoward given their age. In principle, to finish this project, after sourcing the remaining parts, you will need to hook the jacks up to the appropriate pins on the edge card sockets and provide a power supply (not included). Failing that you can just use the modules as spares for your pre-existing ARP 2500."
