Group,

The Russians didn't build anything similar to the ART-13.  However, they
manufactured their own version of the BC-348Q, in the 50's. The Soviet
military nomenclature for their version is US9. I own a specimen which was
manufactured in 1952 and I have a set of spare  tubes for it  with 1972
manufacturing dates. The tubes are direct equivalents of the US  metal octal
types which were used in the -Q model BC-348.  The nomenclature of course is
Cyrillic on the US9. There are a couple of differences between the original
BC-348 and the US9: The US9 has all plastic knobs except the band switch,
the US9 has a fuse for the 24V primary on the front panel (makes sense!),
next to the dial light dimmer knob. Also, the US9 instead of the 2  1/4"
headphone jacks, has just one set of banana jacks for headphones. The
standard Russian headphones have banana plugs, as well as the standard
military keys. I'll check the screws in the US9 one of these days to see
whether they were standard US or metric.
I know for a fact, that in the 60's the original dynamotors in the US9 were
later replaced with exact plug-in solid-state inverter power supplies. I'm
trying to get one of these through my European surplus contacts...
The Russians also made a VHF transceiver for aircraft (they used them on the
MIG-15's, 17's and 19's) which was not an exact copy - I don't remember the
Soviet military nomenclature right now  -  but still quite similar to the
SCR-522, similar enough to clearly see the heritage...

  I have seen BC-348s with cyrillic legends on the front panel, and
always took these to be Lend-Lease items of U.S. origin.

  Did the russians actually build their own ART-13s???
