SUB-MODULES CURRENTLY IN PRODUCTION
/ 4002 EXPONENTIAL MODULES
(for the ARP 2500) - 79.00
features improved thermal properties - excellent tracking, military
grade components. Special order.
VCA MODULES (for the ARP 2500 multimode
filter) - 89.00
specify: 1P, 2N OR 3P. These improved discrete VCA modules exhibit
much better control voltage feed-through specs than their ARP predecessors.
HIGH IMPEDANCE OP AMP (for the
ARP 3604 keyboard) - 48.00
module is for the memory circuit in the early 2600 keyboard controller.
Low profile design facilitates installation and calibration.
24db LOWPASS VCF - (for the ARP
2600 and Soloist) - 379.00
original 2600 filter is now available from CMS. The 4012 is ARP's
hybrid version of the 4 pole ladder filter similar to the filter
used by Moog. Use as a direct replacement for the post 1975, chip
filter (4072), or as a solution to the unstable behavior of the
original 4012s, (Symptoms include: clicking, chirping, short-wave
noises, loss of gain and high end when the filter Fc is high). With
no alterations in the original circuit design, this module features
improved construction techniques over the original to guarantee
click free, stable operation all the way up to 35khz. Low noise,
precisely matched, ultra-linear transistors ensure an unmistakable
vintage sound. Tested to more stringent standards than original
factory test procedures. Directly replaces 4012, 4013 and 4072 modules.
The 4012cx installation Kit can be installed by a competent tech.
Comes compete with easy installation instructions. Free installation
and calibration when installed at CMS.
BALANCED MODULATOR (for the ARP
2600 or 2500) - 225.00
to exact factory specs using premium grade components. Improved
high slew rate output stage.
also offer a 4014 adapter board for older 2500 Ring Mod replacements.
Special order part # 4107.
SAMPLE AND HOLD (for the ARP 2600)
to factory specs with ultra low drift components.
VCA MODULE (for the ARP 2600) -
components and better power supply isolation result in lower distortion
and a much faster transfer function. Built from original ARP blueprints
and fully tested beyond factory parameters. Very transparent compared
to original 4019's
A.D.S.R. MODULE (for the ARP 2600)
to exact factory specs. Uses discrete transistors for reliable,
high speed performance.
NOISE GENERATOR (for the ARP 2600)
genuine analog white noise source. Tested using factory procedures
for proper spectral density and stability.
4023 12db LOWPASS VCF - (for the ARP Odyssey 2800) - 279.00
The original 2800 filter is now available from CMS. This filter is a 12 Db 2nd order lowpass filter based on the famous ARP 2500 multimode filter.
4027 PRECISION VCO (for the ARP 2600, Soloist , Little Bro & Explorer) - 349.00
The older 2600 oscillators are now available again! The similar numbers were a deliberate attempt by the factory to divert attention away from this major change. The 4027 is a much more complex and expensive circuit than the 4027-1. The 4027 is a totally discrete oscillator, somewhat similar to the minimoog VCO (version1) with much better exponential generator and temperature compensation circuitry. Built to exact factory specs, and tested using original factory criteria. We use only OEM parts to assure stable pitch and uniform tracking with the other ARP VCO's in your system. This special design by CMS features an on-board high frequency trim pot, so you can install this classic VCO in any version 2600 without any modifications! Directly replaces: 4011, 4017, 4027, and 4027-1 modules.
PRECISION VCO (for the
ARP 2600, Soloist , Little Bro & Explorer) - 189.00
to exact factory specs, and tested using original factory criteria.
We use only OEM parts to assure stable pitch and uniform tracking
with the other ARP VCO's in your system. Directly replaces: 4011,
4017, 4027, and 4027-1 modules. Beware of cheap imitations using parts "as close as possible".
LOWPASS FILTER (for the ARP 2601)
OEM unit. Upgraded to 28Khz and re-tested to factory specs. Also
features an improved output stage. Guaranteed to be temperature
stable and free of control voltage feed-through. Limited availability.
LOWPASS FILTER (for the ARP Odyssey
II, and Avatar) - 275.00
OEM unit. Upgraded to 28Khz and re-tested to factory specs.
to be temperature stable and free of control voltage feed-through.
