ARP Quadra 1978 - Black *Restored*

This classic behemoth has had many, many hours put into it to bring it back to its former glory.
If you're looking for a Quadra, I think this one is well worth considering as it is now a fully working, reliable synth with a lot of care and attention put into it.

I will purchase a FLIGHT CASE for this synth prior to shipping, at my cost.

Work Carried out:

• Complete power supply rebuild (including all new regulators and capacitors)
• COMPLETE polarized capacitor replacement throughout the ENTIRE synth (all tants and electrolytics)
• ARP Filter modules removed and re-capped (using audio grade caps in the filter audio path)
• Brand new Keyboard control PCB fitted (battery damage had ruined the original board)
• Brand new Memory backup battery fitted (average 20-25 year life span)
• Extensive Logic chip replacement.
• Keybed stripped, chassis painted and keys re-bushed (feels like new again)
• All sliders and switches completely stripped, cleaned, re-lubricated (and replaced with NOS where needed)
• Brand new set of slider knobs fitted
• Full Calibration

This synth will also be supplied with a beautiful (and extremely rare) original bound service manual (see photos)

The not so great:

The touch sensitive bar that runs underneath the keybed is not as sensitive as it probably once was, if this bothers you there are a couple of vendors out there that sell replacements.

There are a few scuffs and blemishes (see photos)

A dent in the bottom of the enclosure at the back of the synth (see photo)
