It appears to have an original red Surrey Electronics case, compared to this racked one. You'll find a spec sheet there as well.

"Surrey Electronics Spectrum Shifter

Uses the same principle as Bode frequency shifter. Ostensibly for 'Howl Reduction' but capable of some very interesting effects. Essentially, unlike a pitch shifter, a frequency shifter does not preserve the harmonic relationships in the input signal. In practice this means the output quickly starts to deviate from what is going in and extra tones are added which then interact and interfere with the source producing new harmonics and drones. Very good with other fx. Great studio addition as you can plug allsorts in not just for vocals.

31cm x 27cm x 24cm
240v unit

Mono input and output via 1/4" jacks on the rear. (standard 'guitar' Jacks)
some scuffs and slider plastic is missing, did not replace as does not affect use. See photos."

As far as I can tell, nothing appears to be damaged.
This is an absolute rarity!

ARP 2500 Modular Synthesizer w/ Pair of Fully Loaded Wing Cabinets

This one was spotted and sent in via
M Me.

"Vintage ARP 2500 Modular Synthesizer system. Accompanying the ARP 2500 main cabinet is a pair of fully loaded wing cabinets. The main cabinet and keyboard were fully restored by Phil Cirocco (CMS) around 2011 as well were most of the modules in the wing cabinets. However the system has not been powered up or played since 2018 when I moved from Los Angeles to Tucson Arizona. It was working perfectly in 2018. Since sitting for 7 years the system will most likely need some small service to get it back to perfect. IT IS UNTESTED AND WILL NOT BE TESTED. IT IS BEING SOLD AS IS.

The previous service was meticulously done to satisfy my serious demand for the system to remain as original as possible. No modifications were done and all parts replaced with original or appropriate parts. The system is hyper clean in person and was clearly babied. It was used on notable lp's. You may live a 100 more years but will likely never find a better more complete ARP 2500 for sale. This system is priceless and was the most expensive new instrument when it was produced in the early 1970's.

I collected and played many Moog, ARP and Buchla modular systems. However owning so many systems became a burden. As well, switching between using Moog, ARP and Buchla took too much bandwidth. I sold all of my Buchla systems and this is my last and best ARP piece from my massive collection. Time for someone else to own it

CAN BE PICKED UP IN TUCSON AZ OR I CAN DELIVER TO LOS ANGELES CA"

"The sampler has been completely refurbished. The casing has been painted black. All tact switches have been replaced, the old LCD with a new LED and pad sensors. Additionally, I have installed the Gotek FDD emulator (32GB Sandisk pendrive included), the latest Vimana 3.15B OS, max RAM memory and multivoltage power supply. This means that it does not need step up or step down converters to work! The voltage switches automatically depending on the place in the world. It accepts AC voltage from 65 to 265V. This is probably the only such version in the world. I was going to replace the LCD window, as it has a few scratches, but I'll leave that to the new owner. The glass is available on eBay, and replacement is easy (double-sided tape). Insured shipment."
