I reckon 1ж24б and 1ж29б -в then plus there's a few others I've been meaning to get for a while such as some 6с17к-в and 6ж52п so I'll have to search for a store that has all and can combine the postage.
Prices seem to vary considerably and delivery time up to 3 months! all looks a little dodgy....

Although I have not used any yet, apart from a few tests, the Russian Nuvistors I bought have long leads so can more readily be used directly. I have to say though they follow the usual Russian practice with leaded valves in having them all over the place (although it does follow the specification) so it does take some deduction to determine which lead is which. A not uncommon trait is to have a lead shown on the diagram but is actually cut off on the base, although I cannot remember if that was the case with these.
I have bought some valves from the Ukraine since the war started but I decided to track down a supplier away from the front line. Some appear to be within a few miles of the strife. The supplier I used was in Odessa and the valves were delivered promptly (I remember not how long but maybe 1 to 2 weeks). This was Just before the Russians started targetting the grain silos in Odessa but I think you would be unlucky to get poor service.
Russia is obviously out of bounds and the only ones I have seen from there, which appear to have been stopped when I last looked, were routed through China.
Prices seem to have increased, as might be expected, but the best I have seen seem to be from the Ukraine. Sellers do seem to keep an eye on the market though.
