The longwave might be so insensitive because they dont want you to hear any propaganda from the west. Remember what part of the century it was produced. Germany did this before ww2

Ernest has given me some more links to a Russian site that has lots of information on Russian/USSR radios ..

With regards to the valves they should be similar to western types.. just that some letters in the roman alphabet like Q are not found in Cyrillic. Also the J will be transliterated to the cyrillic equivalents.

A lot of western technology went to the Soviets during WW2 'cos "they were on our side" for a while. Tizzard had something to do with this?

Single-ended octals (the 6Sxx series) are from that period. Some local factories made variations with small "G" style envelopes.

After translating and reading the text, I can see that the 6SA7, 6SK7, 6SQ7 and 6SJ7 are exact equivalents of the original Soviet valves. The output valve should be a 6L6 rather than 6V6. The tuning indicator is a 6E5C, which I guess is a 6E5 with octal base. The 6E5 needed little voltage change to get a good deflection, so that would make sense.

The radio went through various changes in valve line-up, so my radio was made in 1952 just before they changed out the 6SQ7 for a 6X6S. Earlier radios used the triode in the 6SQ7 instead of the separate AF pentode.
