The Russians referred to the four B-29s which were left in Russia, at an airfield near Vladivostok, as "Dar Bozhie" (Gifts from God).
During WWII, the Russians were officially "neutral" towards Japan, and they allowed US planes to land on Russian territory, only in emergency conditions. The US B-29 crews were interned as "guests" at a resort near the Black Sea resort of Sochi, and wre treated as honored guests, and not as POWs, but at the same time, taken out of action.
Then the day after the surrender, the Russians then declared war against Japan.
Similarly, they copied the C-47 / DC-3, IIRC, it becane the Antonov AN-18. (AHTOHOB AH-18) Which larter earned the NATO designation as "Cub".
The History Channel shows the B-29 proogram occasionally, and one part of it shows the open to the public display of the project in progress.
One part of that display shows their copies of our aircraft radios, and the tubes that they copied, and one in perticular definitely looks like a 6B4G (their 6C4C / 6S4S).
The 6C33C contains two triodes in the same jug, but the difference is that the two sections are parallel connected, and it has two separate filaments.
Gives them the option of 6 or 12V operation, or simply running half the tube. Hmmm, half a 6C33C is a 6C41C, and a 6C19C-V is basically half a 6C41C...
