Orangey-Brown Accumulation (Buchla 100)
video upload by Memetune Studio
"This is a live performance on an original Buchla 100 from the late 1960s, using the Concrete Box™ , and TX-6 mixer
The patch uses 3 loopers and 2 delays, plus a very old Dynacord VRS23 reverb (which is adding some slightly woozy pitch-bendy-ness to the reverb)
The Buchla has a really basic patch - just one Sine-Saw VCO into the Sharp Cutoff Filter (Lowpass section). There's some cutoff mod from the keyboard capacitance voltage (which is why I'm wiggling my fingers in a rather silly-looking way)
The vintage Buchla 100 sounds so natural, rich and organic, I love it - almost like an acoustic instrument - a brassy, beautiful tone from the saw waves
Also, there's a second VCO (square) going into the HPF section of the Sharp Cutoff Filter (which is independent from the lowpass section in this mode) for the low drones
It builds up a bit like the many fallen leaves which have accumulated upon the now wintery lawn I am gazing upon"

Moog Synamps

1080 details follow (1127 further below). Pics of the inside for both below.

"Extremely rare, extremely heavy, and not fully functional: here is the fabled Synamp from Moog, interestingly a native UK voltage example. The power amp is not working, and the spring tank needs to be replaced. But this is what it does have working well even before servicing: a vintage Moog graphic with drive level control and overload LED, and four channels of comprehensive Moog parametric EQ, each with input gain with overload LED and effects send level, and three sweepable bands for each channel. Cosmetically, check the photos. The important parts are a good 7/10, but some of the rest is not. It's not pristine for sure. But it is a very special piece. CORRECTION: the tatty but original Moog wooden road case goes with the second Synamp in this auction, not this one. That means that there is no reverb tank at all with this one (the tank sits in one of the wooden case lids) - but a pretty simple job to house and connect a replacement. This example is still seriously heavy and solid without the wooden case.
There will be a second Synamp in this auction in non-working condition, and possibly the massive speaker cabinets (as seen) that they were designed to work with - though their huge power could only really be used in a decent sized space. See lots 30464 and 30465."

"Listed as 'modular' - but it's a semi-modular, 4-voice paraphonic synth, or mono synth, with on-board effects (reverb, delays, phaser, flanger, chorus), internal sequencer and interpolator (innovative design where sequencing can combine morphing of the oscillators, filter, LFO and envelopes), with patch memories. Very useful multi-mode filter (LP, BP, HP), with digital and analogue filter circuits. Good connectivity including midi (front and rear) for this to be the centre of your modular universe.....and it sounds wonderful and is built like a tank. Version 2 firmware with version 1 livery. This is the more expensive desktop version which can be rehoused in a eurorack case by simply disconnecting from the internal power bus and removing from the case. The case does however provide benefits for connectivity, e.g., the 1/4 inch jack inputs to run any external signal (mono or stereo) via the effects section. A future classic?"

"This is a unique opportunity to buy a monster synth, that is also a piece of synth pop history. Two cabinets plus the original keyboard, all lids, interconnection cables and original manual included. The first cabinet is a Roland System-700 Lab is one of the rarest and most sought-after modular synthesizers ever built.
Introduced in 1976 as part of Roland’s legendary System-700 series, the Lab version was designed as a compact, self-contained modular laboratory for advanced sound design, research, and education — but with the same discrete analog circuitry, massive sound, and build quality as the full studio system.
This one was owned by Bill Vorn, keyboardist of the synth-pop band Rational Youth, used in the following albums dated 1981 to 1983 : Rational Youth, Saturdays in Silesia, City of Night and I want to see the light, as reported in the certification signed by Bill Vorn himself, provided in the item. The second one is another original SYS 700 one, connected and internally cabled to the main one by means of the original cable, with the super rare modules that you see in the picture: an additional, multimode filter, the great output module and… a professionally custom module with a perfect ARP 2600 VCF clone… plus other stuff.
All the best Sys 700 modules, featuring the iconic vintage Roland tone — warm and incredibly dynamic — and offers an extraordinary range of sonic possibilities thanks to its flexible patch architecture. Perfect for collectors, professional studios, or synth enthusiasts looking for a centerpiece instrument with historical and musical significance. The system sports a comprehensive modular architecture with 3 oscillators, 2 filters, 2 VCAs, 6 envelopes (!), mixer, phaser, spring reverb (HUGE) and …utilities.
Legendary System-700 sound — powerful basses, evolving textures, experimental tones. What to say more? Fully functional and in very good cosmetic condition with minor signs of use. You will never find another in such condition. Last call…"

"Programmable analog drum machine from East Germany, often tagged as the "east block TR-808". I think it deserves better than this comparision, since it's a very nice sounding drum machine on its own, with many features for the time (MIDI IN and OUT - sync and trigger, stereo output, optional trigger inputs and individual outputs etc)
Unit was serviced, calibrated and is in fully working order. It has the latest firmware which fix the MIDI timing issue earlier units had. If you don't know these units check the quick demo I made with this very unit. (led blinking is of course only due to video refresh rate, they don't blink in real) I serviced several of those units through the years. Cosmetic is in excellent condition with only very little wear and scuff."

"Buchla / BEMI 208e rev3 module in like new condition. All is good working, better than from the factory. I installed NOS µA726 and (re)calibrated the oscillators tracking, they have similar range and track well, the CO over 4 octaves and the MO over 5 octaves. I scaled the AM so that it reaches full level with the slider all the way up (and not around mid-course like on many units, which twists the waverform and causes modulation at double frequency). I can install it in a powered boat for standalone use. I can do modifications such as stiffer pots, Rogan knobs, dedicated out for each LPG or the CO (to sync the VCS3 Card's oscillator and FM the MO), reverb mix CV input, noise generator... Happy to discuss this with the buyer."
