video of the new VG Line RITM-2 posted here.
"The Ritm-2 synthesizer made by VG-Line is a direct recreation of the ’80s Soviet one-osc monophonic analogue synthesizer, РИТМ-2 also known as Ritm Dva or Rhythm-2, in a form of small-sized desktop module, which can be controlled via MIDI or CV/Gate. The original model was itself inspired by small-sized analog Moog synthesizers and the sound of this little synth was pretty close to Moog but it had number of distinctive properties making it unique: A specific VCO with unusual distorted triangle waveform, VCO waveform mixer, a bit more non-linearity in the VCA and a little distortion in the output stage. Also, the original model had two full-featured ADSR envelopes on-board — a pretty rare feature for this class of monosynths. One of these envelope generators had the Cycle feature.
The new desktop synthesizer has the almost identical set of features and controls as the original, but it also has a number of improvements:
More reliable and stable modern power supply. No more 20 minutes warm-up for the stable tune!
MIDI In and Thru
LFO rate can be synchronized with the MIDI Clock
LFO rate knob works in the traditional direction, opposite to the original, reversed direction
Note Velocity can be assigned to VCA level (selectable)

"AVP PolyRhythm dual analog filter + phaser. These are extremely rare as only 20 were ever made. It has two VCFs: Polivoks filter and Ritm-2 filter. It uses authentic Soviet components and circuity in accordance with well-known Soviet synthesizers, produced in USSR back in the 80's and 90's. The Polyvoks has low-pass and band-pass with one input and two outputs (one for each filter) and the Ritm-2 has low-pass with one input and one output. It has an internal LFO and CV inputs for both sides.
"It was manufactured by Kirovsky musical instruments' factory in 1980s, designer - Viktor Nikulin. The EMI Ritm 2 is an one-voice keyboard analog synthesizer designed for solo, ensembles and orchestral playing musical compositions of any genre. It can be used both in studio & on live concerts.

"Ritm-1 is a solid keyboard organ manufactured by the Kirov Factory, having a 5-octave keyboard providing the possibility of split sounds of the right and the left sections, a built-in rhytm box and the function of auto accompaniment with various styles.
"AVP Synth is a Russian brand manufacturing synthesizers and drum machines, as well as other audio related products. 
"This synthesizer was manufactured by Kirovsky musical instruments' factory in 1984, designer - Viktor Nikulin. The EMI Ritm 2 is an one-voice keyboard synthesizer designed for solo, ensembles and orchestral playing musical compositions of any genre. It can be used both for educational needs and creating different musical effects. This synthesizer can be used with an acoustic amplifier which has a response of 0,775. There is a possibility to use a low frequency amplifier such as radio receiver, TV and tape recorder. The quality of the sounding depends on an acoustic amplifier.
