Old USSR fx circuits (mu-stage in 1983?)

[Vasiliok]

Hi all!

A buddy of mine has scanned and sent me this old soviet fx circuits!

Most interesting circuit - the one which uses mu-stage!
Wow! They knew mu-stage sounds cool with electric guitar!  :shock:



Circuits could be found here:

Hey Vas,

nice fuzz history lesson!  :-)
Jfet overdrive?
Octaviertypes?

[Vasiliok]

thanks!
Yeah! Interesting designs for 1983 year! (((=

and post translation?
i can take translation and individual circuits and
create an "english version".

Thanks, very Interesting.

Is the muamp ckt *specifically* for guitar in that article?  The muamp has been around for a long time, even the JFET version - i've seen it in 1960's stuff.

It going the be hard using an on-line transfation tool for those scanned images!

Thanks Vasiliok, most entertaining!
I wonder if our old friend U.S.Patoff provided any inspiration for these?  :roll:

Interesting contrast between the "closedness" of the cold war era and the openess of the internet era.

Cool, thanks for sharing the schematics with us.

...the "moo"-stage, aka "SRPP" is based on a -of course- tube-circuit, first patented in 1940...
(and I`ve seen it in a 2-tube 3channel-preamp pedal with extremely high Z-in, recently...)

[Vasiliok]

Thnaks guys!

I'm glad you like circuits!

Puretube:
which amp?
I'm sure you're very aware of the continuing popularity of SRPP stages in the high-end hifi world.

[puretube]

not amp, but pre-amp pedal;
saw it here:

(the "Tube-Meister" : not available on the market, yet, though...);

BTW.: Mr. Z. Vex knows why he calls for hi-imp. inputs!

I am aware: was lucky to be able to provide some information to this article:
