The Soviet Pentode is a true Class A tube saturation Colour Module. The Soviet Pentode is built with sub-miniature, military-grade, USSR made, NOS thermionic valve.
The Soviet Pentode can operate in Triode or the Pentode Mode. Each mode offers different Saturation characteristic which results in different tonal results.
The Triode Mode has lower gain, produces mainly second harmonics and the sound is warmer, more mellow.
The Pentode Mode delivers 3dB higher gain, overdrives much quicker, produces more of 3rd and 5th harmonics and the sound is more bright and crisp.
Both Operation Modes add natively occurring tube compression.
The Module does not use any DC/DC converter and does not contain dangerous high voltage.
Low-Power Miniature Valve
The Soviet Pentode Colour Module uses the Low-Power NOS Military Valve designed for operation in Low-Voltage conditions.
No under-voltage of the Tube is happening. The Soviet Pentode valve works according to the specification sheet producing a rich palette of harmonics.
Important User Note!
The Soviet Pentode requires time to heat-up. Allow 5 minutes wait time to ensure proper operation of the Tube Colour Module.

The US Pentode Compared to the Soviet
The US Pentode Colour Module shares some similarities with the Soviet Pentode Colour Module. Both Colour Modules have the Pentode/Triode selectable operation mode and can operate at lower, safe voltage without sacrificing the performance.
The difference is in the type of tonal results which both tube colour modules can provide.
The Soviet Pentode produces darker and a bit lo-fi tone, especially in the Triode mode. If you are looking for an old-school sound for your synth or vocal, the Soviet Pentode is a perfect choice.
The US Pentode will produce more “Hi-Fi” tone, brighter, with a glass-like shine. If you wish to add some sparkles to the guitar or vocal, you should choose the US Pentode.

I took a moment to try them on stems. The Soviet Pentode is amazing!
Perfect to add that tube amp-like breakup on a clean guitar track for example.
The Line Driver seemed to be the cleanest of all three.
I definitively need to try the different jumper configurations. Would be interested to have your opinion on this one!
