ARP Little Brother

“This Little Brother has just been refurbished by Synthchaser, including the following work:

New sliders installed
Power supply recapped (high quality, high temperature 105 deg C capacitors used for the filter capacitors)
All tantalum capacitors replaced (except on 4027 Oscillator submodule which was not touched)
All CMOS and op amp ICs replaced
New pitch bend knob
Tested with a vintage ARP Axxe

While it works great and looks reasonable, my perfectionist nature requires the disclosure of the following cosmetic flaws. The ARP Little Brother tag is missing from the front of the unit. There is a small hole drilled above the Reed switch (the other small hole is from the factory, and used to access a calibration trimmer). The Reed and Fuzz switches were replaced with NOS switches for proper operation, however only black switches were available. The Vibrato Delay switch cap is missing. The lamp on the power switch does not illuminate. There is a scratch on the panel by the vibrato delay.” Click here to visit listing on eBay

It powers up, however, I have no way to test it so I’m selling for parts. It worked when it was last used (5 years ago) but electrolytic caps dry out over time so I’d give it a tune up. Sliders are stiff, too, and need some lubrication. Fortunately, there aren’t a lot of parts, and the chassis provides easy access, so any repairs or mods / upgrades should be very straightforward.

This synth sounds fantastic – see the videos on youtube.

It is missing the bottom plate. This seems common with the earlier model (2151 rather than 2153).

Whoever takes the time to rejuvenate this synth is going to have an amazing sounding piece of modular synth history.” Click here to visit listing on eBay

ARP Odyssey and ARP Little Brother

arp “Cosmetic condition is a fair minus. Both instruments suffered some finish damage from where they were stored in a case for an extensive period of time. Both these items have had extensive restoration service and look great on the inside. Full control panel cleaning. Power supplies have been totally rebuilt and premium caps were used. ICs and opamps have been placed into sockets and replaced, new cts trimmer pots throughout both instruments, new keyboard bushings, new set of white slider caps, all the hardware had to be replaced. New cts jacks on both instruments and the audio input/output rca jack on both were switched to more popular connections. Cables to connect both of these instruments together will be included. Too much to list everything. ”

ARP Little Brother

little brother “Up for auction is an ARP Little Brother 2953.

Is it important to note that the physical condition of this unit is fair, but has not been fully tested. This is due to the fact that the ARP Odyssey 2800 that it originally came with (please see my other auction) does not currently produce audio. With this being said, there is a chance that the unit works perfectly, but there is also a chance that it does not function at all.” Click here to visit listing on eBay

ARP Axxe and ARP Little Brother

lb “Selling a working ARP Little Brother Collectible Vintage Synthesizer expansion unit in overall nice cosmetic condition. Checked out by local electronic shop and said to be working. Also including is the original ARP 2313 Synthesizer that is not working. Shop did not have schematic to diagnose problem when I had it there but I am told all components are not hard to get once the problem is diagnosed. They just did not want to take time to scope it with no schematic. I was able to download a 2300 service manual which looks very similar but this was after I picked it up from the shop so they probably could use that to diagnose but I am just going to sell it as is along with the Little Brother and let the buyer fix it or have someone fix it. It also is in very ice cosmetic condition. Both are rare early synthesizers and the 2313 is well worth fixing” Click here to visit listing on eBay

ARP Little Brother

little brother” Rare vintage 1970s ARP Little Brother analog synthesizer expander module. In excellent working and cosmetic condition. 100% complete. This Little Brother sounds as good as it looks. Works well with any standard 1V/octave analog synthesizers. ARP, Moog, Oberheim, etc. You’d be hard-pressed to find another Little Brother this nice as these units are getting harder and harder to find, especially in this condition.” Click here to visit listing on eBay

ARP Axxe and ARP Little Brother


This is a gorgeous little ARP combo in a very old original built case with lid and legs. You can see form the pics that conditon is excellent for the Axxe and overall for both units is pretty good although the Little Brother badge could do with some ‘reinvigorating’.

There is loads of info regarding these items online, but i would definitely say that the Little Brother is a very rare unit on its own, i’ve hardly ever seen these up for sale!!!

I paid a significant amount of money to have everything brought back to full ‘like new’ working order with Saint Eric- the boards have been washed, sliders repaired/lubed and Key contacts polished.” Click here to visit listing on eBay
