I could be wrong about the tube but there are no other markings...
James is a godsend....

What tube is that? It appears to be a sub miniature, and I see it has a socket which is rare on a submini.
edit: looking again and comparing in the other pics the size of the tube compared to the PSU, it's not a sub mini

I believe it is a sub mini. It's smaller than the size of your pinky finger. Look at the size of the capsules. The power supply itself is about 4 inch's wide. I should see what the tubes in the power supply are.
James said if it ever went (or the one on the other side that you can't see) an AC701 is what he would probably have to try next. I believe this to be a proprietary component built by the Radio Institute Popov, St. Petersburg themselves. James could not identify the tube.
Bear in mind that this was designed in 1969 and around 50 prototypes were manufactured in 1970 by the government owned Popov Institute. Had they went into production the design/plans would have gone to Lomo to manufacture. Unfortunately around that time solid state mics were becoming popular (even in Russia).
So possibly this tube would match a Lomo tube out there, I really don't know. I just hope the mic keeps going as she has quite a reach and a sound unlike any other tube mic I've ever owned.
James saved the top capsule and kept the original design. Unfortunately he couldn't find any sea foam green plastic... The capsules seem to match dead on, so I couldn't be happier.
