tubes, and marked Made in England
I also have a Realistic Lifetime (radio shack) type 80, which is clearly an
indirectly heated tube, and also clearly
Russian made, but marked Made in England.
Before about 1990, there was a very high (like 35% or so) import
duty rate for importing goods from the USSR into the USA.
That punitive duty didn't apply to most of the EU, so a lot of
Russian tubes bound for the USA were transshipped via England
and western European countries, to avoid the duty. Most
Customs officials, not being tube aficionados, and tubes
not being a huge share or international commerce, didn't know
or care... but, in fact some of the places that imported Soviet
tubes that were mislabelled as not being Russian, got busted.
Unca Sam may not care much about tube provenance, but he
does want his tax money...
