4001
/ 4002 EXPONENTIAL MODULES
(for the ARP 2500) - 89.00
Rev-F
features improved thermal properties - excellent tracking, military
grade components. Special order.
4005cx
VCA MODULES (for the ARP 2500 multimode
filter) - 89.00
Please
specify: 1P, 2N OR 3P. These improved discrete VCA modules exhibit
much better control voltage feed-through specs than their ARP predecessors.
Special order.
4009
HIGH IMPEDANCE OP AMP (for the
ARP 3604 keyboard) - 64.00
This
module is for the memory circuit in the early 2600 keyboard controller.
Low profile design facilitates installation and calibration.
4012CX
24db LOWPASS VCF - (for the ARP
2600, 2700 & CMS 2607) - 399.00
The
original 2600 filter is now available from CMS. The 4012 is ARP's
hybrid version of the 4 pole ladder filter somewhat similar to the
filter used by Moog but there are significant design and audio differences.
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.
4014CX
BALANCED MODULATOR (for the ARP
2600, 2500, CMS 2607) - 225.00
Built
to exact factory specs using premium grade components. Improved
high slew rate output stage and input stage.
We
also offer a 4014 adapter board for older 2500 Ring Mod replacements.
Special order part # 4107.
4015
SAMPLE AND HOLD (for the ARP 2600,
CMS 2607) - 189.00
Built
to factory specs with ultra low drift components.
4019CX
VCA MODULE (for the ARP 2600, CMS
2607) - 225.00
Improved
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
4020
A.D.S.R. MODULE (for the ARP 2600)
- 179.00
Second
generation envelope generator for the 2600. Also coined by the factory
as the "simplified envelope generator". Built to exact
factory specs. Uses discrete transistors for reliable, high speed
performance.
4022
NOISE GENERATOR (for the ARP 2600,
CMS 2607) - 75.00
A
genuine analog white noise source. Tested using factory procedures
for proper spectral density and stability.
4023
12db LOWPASS VCF - (for the ARP
Odyssey 2800) - 229.00
The
original 2800 filter is now available from CMS. This filter is a
12 Db 2nd order low pass filter based on the famous ARP 2500 multimode
filter.
4027-1
PRECISION VCO (for the ARP 2600,
Soloist , Little Bro & Explorer) - 189.00
This
is the second generation VCO used in all ARP 2600s made from August
of 1972 to 1980. Designed by Phil Dodds. 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. Directly replaces: 4011, 4017, 4027, and
4027-1 modules. Beware of cheap imitations using parts "as
close as possible".
NEW
- 4035CX 24 Db LOWPASS FILTER -
(for the ARP Odyssey II, and Avatar) -
$229.00
CMS
has come up with a great sounding filter for the ARP Odyssey 2!
The
4035 filter was the second version filter used in the ARP Odyssey.
It is ARPs version of the Moog ladder filter for the Odyssey.
After
years of development and listening tests, we have come up with a
much improved version of the 4035. It exhibits significantly lower
noise and better low end response compared to the original without
any changes to the original circuit design. It also has a spectacular
sound quality.
The original ARP 4035 was also prone to significant gain loss when
the filter was all the way open. The gurus at CMS have eliminated
this annoying defect resulting in a more powerful sound. Guaranteed
to be temperature stable and free of control voltage feed-through.
There
is more!
Now you can have ARPs version of the Moog ladder filter installed
in your Odyssey 2 without giving up your original filter! Or vice
versa. Please check out the new 2829
secondary filter for the ARP Odyssey 2 .
NEW
- 4041 A.D.S.R. MODULE (for the
ARP 2600, CMS 2607) - 225.00
Built
to exact factory specs. This is the exact envelope generator circuit
from the ARP 2500 in a sub-module form for use in the 2600. It was
used in very early 2600s as the ADSR module. It uses discrete transistors
for reliable, high speed performance. Use as a drop in ADSR replacement
upgrade for your 2600. Includes an additional negative output pin
that can be wired to a front panel output jack.
4072
LOWPASS FILTER (for the ARP 2600)
- 299.00
Second
generation low pass filter for the ARP 2600. Genuine 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.
4075
LOWPASS FILTER (for the ARP Odyssey
II, and Avatar) - 225.00
Third
generation filter used in the ARP Odyssey 2 and Avatar. Genuine
OEM unit. Upgraded to 28Khz and re-tested to factory specs. Guaranteed
to be temperature stable and free of control voltage feed-through.
