Re: [Amateur-repairs] Creating a LSB and USB Test Signal!!

Thanks Gary,, will need my son to come over and help me move the Eddystone off the bench, BUT!!!!! Saturday and Sunday are Football Days, love the sport since I was 10 years old.. My wife is a big Dallas fan so that did not go over to good… Ever since the Chargers moved from San Diego to LA, I gave up on them a long time ago.. Only one more to Go Down, Chiefs!! Then we have some new blood in the Super Bowl..

I also love to see the underdog beat up on the So Called, Best Team… As they say, "On Any Given Sunday"  J

Robert,
Good advice.
I am no expert but I believe you can't rely too heavily on any tube tester.  The actual circuit where the tube goes is the best tester.

I downloaded the 51s1 manual just to have a look.  The BFO is one tube.  I would try another, there are probably many types that could substitute
there if you don't have a good spare.  I am thinking it maybe has a filament to cathode short or leakage of some kind that lets the AC filament signal onto
the BFO signal.  But just a guess.
