  • RCA - customers advice wanted

    I was offered to buy a used RCA ECC81 tube. I've never tried this brand, but 10$ seems fair, if the tube is ok.

    Yes or no..?

    It may be the photo angle, but the plate looks like the smaller, folded over design. Not (to my knowledge) used in USA / UK / Western Europe manufactured tubes. Ask for another photo, rolled around a few degrees, to see the plate face on. Pete.

      What would I be looking for? I can ask the seller, no problem.

          Yes, I meant, what would I be looking for on the plate? I'll see if I can get some pictures of the plate...

            Is the plate made from 2 pieces, crimped together at both sides http://ep.yimg.com/ca/I/thetubestore_2143_16820509 (Western) or 1 piece, crimped one side, wrapped round the other http://ep.yimg.com/ca/I/thetubestore_2141_11457145 (Eastern)?
            Linked tube pics are to show the design types I'm trying to describe.

              The dude selling the tube said: Looks as if each plate is made out of one piece.

                In that case I think that it's probably just branded RCA but was made in Eastern Europe. It may be fine ($10 is cheap enough), just don't count on it being a USA made tube, that the RCA brand might lead you to.

                    In what is seen, the shape of the bulb is typically RCA (USA). Looks as an older model than the "traditional" with two straight cuts in the micas. It´s more commonly seen with round getter but also exist with square getter.
                    Perhaps this photo will help identify:

                      The tube is dandy, thanks for helping out!
