m/177 (with 100-120v psu)

price : $280.00


m/177 (with 100-240v psu)

price : $300.00

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.

the model 177 is a high-voltage tube vca with two cv parameters:
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

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 below 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"; results are comparable to "max" feeding nitrous to his supercharged steed on a post-apocalyptic australian byway. in other words: before powering up a model 177: full-body horse-hide body-armor is compulsory!
