[TUD1]

I got this from the Radio club today for $20. It was left in the building when the club moved in 15 years ago, and they had it in the Annex. The Annex consists to two very large rooms filled to the roof with TV and radio stuff. I also got a B&K 445 CRT tester, which I used to test the tube in the set. When I tested the tube in the Annex, it tested 70%. I bring it home, clean all the tubes and tube sockets, and test the tube again. This time, it tested 80%. I leave the tube tester on it for about two minutes, and then walk away. When I come back twenty seconds later, the emissions had fallen to 20%. What gives?! I hope it's just the tube tester acting up. I'd really hate to have to find a new tube for this thing. The cabinet is in exquisite shape, too.
