RE: Looking for 60's 6P3S-E's...




Interesting. Twistd suggested there was a difference in the different vintages, here:

I observed in the ones I sent back today that the 1966 tube had different stamping and different tabs on the plates (1/3 of the size) as compared with the others which were from 79, 82, and 84, which are the same as modern 5881. It has been seen on the web that earlier models were made at the Foton plant vs the Reflektor plant at Saratov.
