"The M666 truely is a devilish module. It´s a synthesizer voice with twin VCOs but it´s a very experimental and brutal one. It makes a lots of noise and distortion. External audio signals can be fed thru and destroyed by the module as well.

The plug and perform simplicity of our stand-alone Triple Six synth has been carefully distilled into Eurorack format. We designed a single module as powerful as an expensive array of traditional VCO/VCF/VCA modules patched together. While no compromise to the true spirit of the original circuit was afforded we worked especially hard to make this one of the most compatible Eurorack instruments available with a generous array of 9 distinct control voltage inputs:

2 for Twin Oscillators Freq.
1 for Threshold (Osc. Gate/Selection/Etc.)
4 for Twin Amplifiers (FX/2nd Osc.)
1 for Signal Shape parameter (filter)
1 for Output Drive parameter
Two VCOs are accompanied by a dual high gain amplifier and some VCAs inside, as well as a filter and a ring modulator. Soundwise the M666 is somewhere in between a detuned radio, a fierce distortion and a noise generator.

Features

Two Oscillators
Dual High Gain Amplifier
VCAs
Filter
Ring Modulator
3 LED Indicators
9 knobs and 5 switches
Audio input (modulation/filter/etc)"

"Little brother of the double-wide 277 the 177 does in mono what big brother does in stereo. The unique design of the M-series 177 delivers not one but two stages of high-gain (& high voltage) vacuum tube signal path without sonic compromise. Harmonics & Bass-Heavy Compression unique to valve topology are delivered with an economy of “hp” real estate (7.5hp!), meager power supply requirements & cost while maintaining Euro Format CV compatibility.

Yes, “high voltage”—no small task for a euro module. Reason being: even the best euro format power supplies were never intended for providing “B+” (arcane engineer speak denoting High Voltage feed for vacuum tubes). Rather than compromise both the operating specs of the tube & capacity of your modular’s power supply the M Series 277 includes a wall-wart to deliver both High Current & High Voltage to the valves without taxing your rack’s supply. Low voltage / low current circuits patch via included ribbon cable & use only a modest amount of power (see specs for details). 177 provides front & rear jacks for the included supply to facilitate access from outside OR inside your rack (cuts down on added wires getting tangled with patch-cords on the frontside).

Use at the end of a patch: Rich tube harmonics & brawny compressed low-end add warmth to your cold digital effects / signals while reinforcing plastic sounding low voltage analog sound.

Use as overdrive effect: Overdrive effects via CV Drive input is a cinch. Use as external input preamplifier: Gain afforded by the 277 is more than adequate to make even the tiny signal of a guitar or microphone patched straight to the input scream. As a modular synth is more than 1000 times louder you may well wonder what happens when such signal is fed through the 177 with controls all set to “eleven”: brutal distortion!

Features

Warm High Voltage Two-Stage Tube VCA
CV Amplitude Input with Attenuator Knob
CV Drive Input with Attenuator Knob
Ample gain for use as External Input Preamplifier
Zero to +5 volt CV-Range compatible w/most LFOs, Envelopes etc.
Compression with Low-End Enhancement
Warms cold digital effects & low-voltage solid-state signals
Included High-Current Power Supply = low impact on your rack’s “built-in” supply
2 CV Lamps: 1 Blue (Amplitude) / 1 Red (Drive)
Slovakian Max. Gain, Twin-Triode Vacuum Tube run at high-voltage
Small: 7.5 hp x 2.275″ Deep"

"Trogotronic M-Series 277 offers a high-gain Vacuum Tube Stereo VCA without sonic compromise. Tube Harmonics, Bass-Heavy Compression & Stereo Imaging are applied with 2 Discrete High-Voltage VCA Circuits.

Yes: “high voltage”—no small task for a euro module. Reason being: even the best euro format power supplies were never intended for providing “B+” (engineer speak denoting High Voltage feed for vacuum tubes). Rather than compromise both the operating specs of the tubes & capacity of your modular’s power supply the M Series 277 includes a wall-wart to deliver both High Current & High Voltage to the valves without taxing your rack’s supply. Low voltage / low current circuits patch via included ribbon cable & use only a modest amount of power (see specs below for details). 277 provides front & rear jacks for the included supply to facilitate access from outside OR inside your rack (cuts down on added wires getting tangled with patch-cords on the frontside).

Use at the end of a patch: Rich tube harmonics & brawny compressed low-end add warmth to your cold digital effects / signals while reinforcing plastic sounding low voltage analog sound.

Use to portray mono signals as vast stereo audio panoramas: The 2 discrete channels run in parallel add depth to mono signals (patched to both inputs) with organic stereo imaging built into the circuit. The same mono signal can be dynamically panned via CV Amplitude inputs.

Use as a stereo overdrive effect: The Drive CV is discrete (1 for each channel independent of the other) so creation of dynamically panning stereo overdrive effects via CV Drive is a cinch.

Use as external input stereo preamplifier: Gain afforded by the 277 is more than adequate to make even the tiny signal of a guitar or microphone patched straight to the input scream. As a modular synth is more than 1000 times louder you may well wonder what happens when such signal is fed through the 277 with controls all set to “eleven”: brutal distortion!

"A compact valve synth capable of the spectacular analog displays that make high voltage tubes essential for any serious electronic music aficionado.

In rare moments of clarity we’ve long glimpsed a brutish dream burning in the solder smoke: A compact valve synth’ capable of the specular analog displays that make high voltage tubes essential for any serious electronic music aficionado. Now the low hanging fruits of our labors are within reach & truly rotten to the core

Yes: “high voltage”—no small task for a euro module. Reason being: even the best euro format power supplies were never intended for providing “B+” (arcane engineer speak denoting High Voltage feed for vacuum tubes). Rather than compromise both the operating specs of the tube & capacity of your modular’s power supply the M Series 676 ships with it’s own. Simply plug in the included wall-wart, give the tube a few seconds to warm up & voila! Tangled in wires already? We get it, and in addition to the power jack on the face there’s another power tap hidden on the rear of the module should you want to get crafty to keep things clean. The advantage is twofold: no capacity is taken from your existing supply and the vacuum tube employed is a common model in current production (so there is no worry should it require replacement after many years of faithful service).

Like any Trogotronic worth its salt the 676 Fury’s functions are not conservative… Meaning, while there are two Main Oscillators, other parts of the circuit can command more complicated frequencies in an intuitive manner. Similarly the Main Oscillators themselves may be applied as filters serving to broaden the utility of the instrument even more so. With regard to BOTH mayhem AND stability 676 Fury’s switch settings offer different parameter reactions: Toggles “down” Oscillators & Track navigate pitch black F-5 electron turbulence; Switched UP same controls “play nice” in crimson livery with accordance to classical form.

Features

All Analog Circuit
2 Main-Oscillators
2 Amplifiers
2 Unique Filter/FX parameters (Drive & Modulation)
Input for use with other audio elements
5 Modular compatible CV inputs for patchable parameter control
1 Master Frequency Control of Oscillators: Track
3 Stabilizer Switches (on for stability, off for mayhem)
Slovakian Max. Gain, Twin-Triode Vacuum Tube run at high voltage
2013 M676 Is Even Better Than Original

Reduced Depth: More Than One Inch More Clearance
Better CV Compatibility: 0 to +5v w/Discrete Onboard Attenuators
Improved Tracking: Revised Performance Osc. Track Parameter
Refined Layout: Allows Tool-Free Access to Vacuum Tube
Improved Pricing: Quicker Assembly = Nearly $30 Off Original Price"

"SUIKO ST-10 is extremely rare and most strange japanese electronic musical instruments
originally made for japanese traditinal music circa. 1980.

WOW! what a strange and exotic design! built in cool woody case with silver metal control panel
and comes with classy black custom suitcase
left side has digital data cassette deck! and right side has internal speaker
it has built in 2 way early digital sequencer,digital data cassette and internal memory
SUIKO ST-10 is one of the most strange design model from the SUIKO line up.
and it's first time to SUIKO ST-10 put on the ebay listing from my collection
(please check out other SUIKO models from my auction list)

SUIKO ST-10 was very expensive and made very limited quantities those days
originaly made for the very small circle of the people who seriously studying japanese traditional music
and never sold at ordinary musical instruments market
so i'ts very hard to find even in Japan nowadays...
this is your first and last chance to get this vintage oriental electronic instruments!

ST-10 is monophonic instrument and has 2 rows of white square button keyboards
this keyboards specially designed for playing glissando easily like koto(japanese harp)
front row of the keyboard is japanese scale,so just playing randomly you can easily get exotic japanese melody!
three sounds are selectable,shakuhachi(japanese bamboo flute),koto(japanese harp) and pipe organ
sounds are very analog, warm and strange!
there are various switches and knobs for special japanese tuning, sustain, volume, memory controls,etc..
back side panel has AUDIO OUT and AC cable

ST10 has 2 ways of recording memory section,digital data cassette memory and digital internal memory
cassette deck of left side is not a usual analog recorder,it's a digital data recorder
such kind of digital data recorder often used with early personal computer in '80s
but I have not ever seen used in electronic instruments
usage is almost same as a usual cassette recoder
but you can change the sound while playback(e.g. koto to shakuhachi)
because it just records playing data like sequencer
other recording section is a digital internal memory
it's a simple early digital sequencer
you can record your play by realtime or note,timing separately"
