REPAIR AND RESTORATION OF ARP 1000 SERIES MODULES AND 2500 SYSTEMS
CMS offers a full array of repair,
restoration and calibration services for the ARP/Tonus 1000 series
modules. CMS has extensive experience repairing, restoring ARP 2000
and 2500 systems. CMS has restored many of the 2500s that are still
being used today for teaching at major colleges across the United
States such as Brown University and the University of Georgia. CMS
has restored ARP 2500s for famous artists like Peter Townshend of
the "Who" and Vince Clarke of Depeche Mode to name a few.
ARP 2500 circuit boards are particularly
delicate and can be easily damaged by a novice tech. This can actually
cost you more money in the long run. We have seen this damage quite
a bit lately when we go to perform estimates on 2500s and 2600s.
Don't let the local tech ruin your valuable vintage instrument.
CMS has in stock, custom replacement boards for several 1000 series
The other typical situation we see
with 2500s coming into the shop is incorrect calibration of the
1000 modules. This is usually due to a tech guessing at the calibration
process. This problem is compounded by the encapsulated sub-modules
used in the 2500 system. CMS has a custom made ARP 4000 series sub-module
tester so we can test your sub-modules as part of the initial diagnostic
procedure. CMS also makes a high quality line of replacement sub-modules
for all the ARP 2500 modules.
Unlike other ARP synthesizers, there
never was a service manual published for the ARP 2500. The official
story is that they never got around to it. ARP discontinued the
2500 in 1976. The 2500s were made so well, ARP did not get many
service requests in the 1970s for 2500s. ARP was out of business
Over the years, CMS/Discrete synthesizers
has created, and is still writing, it's own extensive and detailed
service manual for the 2500. Please don't bother asking for a copy,
It is not for sale at this time. We plan to publish this sometime
in the 2020s.
Send your 2500 system to CMS for a
