ARP PRO/DGX Model 2733


via this auction

"Meticulously overhauled over a whopping 32 hours (!). They usually don't take us this long, but this one had a tricky problem in the digital oscillator section that required a lot of time to sort out. In addition to performing this and any other repairs, we did the following work to this unit:

Touch sensor was replaced with a new one and adjusted. These are usually not working at this point in time.
Power supply capacitors replaced to extend life.
Keyboard rebuilt: replaced bushings, cleaned key contacts and removed and cleaned/polished bus bars.
Removed, adjusted, cleaned, lubed and reinstalled all slide pots.
Cleaned and lubed all switches.
Adjusted tuning.
Cleaned inside and out.

Thanks to all the time, love and money we invested in this unit, it is now working like new again, is totally ready to play, and will hopefully continue to work for a very long time, which makes it a much better purchase than others of its type on the market."
