Moog Memorymoog LAMM - "The Blue Beast" w/ Custom Flight Case SN 1047

via this auction

"A 'regular' Memorymoog in good shape is an incredible find. The Blue Beast's feature set and condition, however, are unmatched. You can see from the photos that, cosmetically, the Blue Beast is exceptional. It sounds better than it looks. The Blue Beast has lived in my home studio and has never been gigged or loaned...

This gorgeous Memorymoog LAMM is an extremely rare and valuable instrument. It is a low serial number (1047) model with black side panels (few had black sides; most are silver). It was thoroughly overhauled in 2013 by Rudi Linhard to become a Lintronics Advanced Memorymoog (LAMM). Lintronics also replaced the original red LEDs with blue LEDs, and replaced the solid black mod wheels with luminescent blue LED wheels, motivating Rudi Linhard to nickname this monster "Blue Beast".

The synth has also been meticulously maintained and further refined by Retrolinear, Inc., one of the premier vintage electronics repair and restoration companies (see Retrolinear's website for their "A-list" band clients). Among other things, Retrolinear replaced the original power supply with an upgraded unit. The new power supply is much lighter. More importantly, it is also silent. (Factory Memorymoogs used a noisy fan.) Retrolinear has also restored or replaced keybed elements and voice chips. All six voices tune.

Included in the sale is a custom flight case fabricated by Mark Dehart at Rock Hard Road Cases. Also included are copies of original Moog Memorymoog service and technical manuals; the Lintronics LAMM manual; and documents showing the LAMM and maintenance work provided."

Vintage ARP Quadra Poly Synthesizer

ARP Quadra demo @ RetroLinear Published on Dec 18, 2018 RetroLinear

via this auction

"We're proud to offer this amazing ARP Quadra for sale. This synth has been painstakingly restored and upgraded to 11 in every way possible. Before we get into specifics on its electronic restoration. Cosmetically speaking this synthesizer is in great condition a solid 8/10 overall. There are signs of use as it's from the late 1970s. The button panel had a few areas which began to split (this is a notorious problem) unfortunately no companies produce replacements. We've fabricated a clear vinyl overlay using quality 3m material which is affixed atop the existing button strip, effectively bolstering the button strip. Both wooden sides have imperfections, metal work overall is clean, few touched up areas. Please be sure to check out all the pictures.

ARP dove head first into the Polysynth race combining the OMNI and SOLUS into one single unit with ADSR, phasing , chorus, arpeggiator , after-touch ,and basic preset memory. These were almost unheard of features in a single unit during the late 1970's- quite ahead of its time. Tonally this synth sounds vast - it produces a massive analog expanse of lush string tones layered in chorus and phasing. Has the signature ARP lead sound as well. Overall it's hard to beat! Independent 1/4" outputs for each section bass, strings, poly and lead synth or stereo left / right output or mono. Lots of output flexibility.

High and mighty- The ARP 2500 w/Don Slepian @ RetroLinear

RetroLinear

"Resurrected from the dead, the mighty ARP2500. A rather lengthy restoration project requiring nearly countless hours of reworking, development of new circuits, reverse engineering failed potted modules to restore operation and improve performance.

Don Slepian paid us a visit and kindly recorded around 20 minutes of musical snippets on the ARP2500 which has been arranged as a single track for your enjoyment!

Many thanks to Don for his musical expertise in steering the ARP2500 and Edwin Kiddo for his 2500!"

Oberheim OB 8 with Midi & Aftertouch

Note: Auction links are affiliate links for which the site may be compensated.

via this auction

"Oberheim OB8 with factory midi in excellent functional and cosmetic condition.The OB 8 comes with a travel case and original OB8 operating manual and patch cassette.

This unit has been modified in 3 ways. 1) The original problematic Panasonic keyboard has been replaced with a new custom Fatar keyboard. This keyboard has a built in aftertouch sensor and was installed by Retrolinear. 2) A sophisticated AT circuit was installed by New England Analog and includes a Pyxis controller and external pressure pad controller. Check out YouTube videos by New England Analog and the Pyxis control system.The Pyxis controller allows the AT to control the VCO, VCF, VCA, and LFO by intensity and speed. A series of toggle switches on the back of the synth allow a variety of AT combinations such as pitch bending up, down, or Osc 1 up and Osc 2 down. Do a search on NEA's Pyxis controller and its capabilities and 3) bass boost which was done by replacing the 100k R505 and R506 resistors with 1M resistors(4) and building a network of 4x of 120K resistors and 0.0056 film caps in series and connecting the small network in parallel to the new 1M resistors.This modification helps create a better low end somewhere in between a standard OBX-A and an OB 8.

This particular unit was in great functional shape when purchased and I invested another $2500 with NEA and Retrolinear on the refurbishing and mods.The rebuild work done includes:
replaced capacitors in PSU
Repaired faulty envelope generator release control on upper four voices
Installed new 5V bridge rectifier
replaced 40109 chips and top voice board 3080 chips
Replaced calibration summing TL 071 Op amp and the two TL 072 output OP amps.
Installed Fatar keyboard with factory aftertouch sensor
Installed aftertouch circuitry and Pyxis AT controller and touch sensor pad
all 16 oscillators tuned and calibrated.
Loaded factory preset patches"

Yamaha CS-60 8-Voice Synthesizer

Note: Auction links are affiliate links for which the site may be compensated.

via this auction

"Fully functional Yamaha CS60 synth. It has just been fully serviced by Retrolinear in the Philadelphia area. Retrolinear knows CS60s very well - they routinely service them for clients, including a few touring musicians who are still using them (Page McConnell of Phish being one of his clients). I have attached the invoice showing details of the work.

Functionally - Every slider, switch, the ribbon controller, and especially important, the aftertouch all work flawlessly. All voices function and are in tune.

Cosmetically - My CS60 is in excellent shape. The silkscreen is near perfect and the entire control panel has only like 2 very small chips and one scrape mark from a fader cap digging into the panel (pictured). The two chips are just above the keybed so don't take away from the cleanliness of the control panel (one is pictured). The tolex on the case is original and in very good condition - again, excellent considering its age.

Overall - This synth was never abused. It spent most of its life in the home of a musician - it was never toured.

The original tolexed hard cover and removable music stand are included - the stand attaches to the inside of the lid. I do not have the original legs. The CS-60 gets you most of the CS-80 sound at a fraction of the cost. The aftertouch truly adds to the expressiveness of the synth."
