[Boatanchors] THE 6EJ7 DID IT!

I found the same low power output problem with my TR3. About 80 watts or less out.
One of the guys on the list here has sent me a couple of Sylvania 6EJ7 tubes, so I am looking
forward to seeing if this will bring it up to full power. Hope so.

> Thanks to all who responded to my post about the wonky TX4C power output. I had installed what I had believed to be a good tested 6EJ7 of noble parentage. However, upon installing a NOS Sylvania tube as suggested by a couple of list members the problem went away and I now have 130 watts output on 40M, 100+ watts on 160, 80 and 20, 80 watts on 15M and 65-70 watts on 10M. I still have not figured out why output on 40M is so much better, but I am not going to worry about it. The transmitter could probably use a new set of finals but the current power output will permit lots of fun operation yet.
