    Did you get this straightened out?
    Not yet. It got put on a back burner while I deal with some other "life" issues. They come more often as we get older.

      So, turned out to be the EL84/6BQ5 outputs. Fortunately, I had a Tube Depot TubeCube 7 amp that uses the same outputs. Swapped those in and the rattling seems to be gone. Put the originals back in and the rattling was back. The Traynor used Russian Sovteks, while the TubeCube used some Chinese things. Since the Traynor is a pretty sweet little amp, I think I'm going to opt for some decent replacements. (Assuming I can get them.)

        That Traynor amp is just bad -pack it up and send to me and I'll send you some $$

        Bad tube for sure.

          Make me an offer. I actually had it in the Trading Post. Packing this thing safely would be a challenge.

              Cool. Let me know whenever you're in the neighborhood.

                Cool, I meant "maybe not" referencing the packing challenge of course!

                  Yup. I think I got that. I think.

                  And to clarify . . . anyone who was in my area could probably get a pretty sweet deal on either my Traynor YCV20 or my H&K Edition Tube 20th Anniversary, just due to saving me shipping, and eBay / Reverb / Craigslist aggravation.

                    Is that the 20 that comes with the greenback?

                      It's got a green trim ring, so that's probably correct.
