Norm, My tube tester says 1 volt and seecial tube type B. I don't want to damage the filament. I could use a 1J6 to try. Ok, I'll try setting the tube tester to 2.Thanks, Dave :Dave : : 1J6 is unusual in some ways. It can operate with zero grid bias. With some bias it draws little current. When you are testing the tube be sure filament is 2 volts. : : 1J6 is rated to 135 volts. You might be reading higher voltage because the 1J6 isn't drawing hardly any current? See if voltage is lower with a new tube. I have some here if you have a hard time getting a 1J6. : : http://frank.pocnet.net/sheets/084/1/1J6G.pdf : :Norm : ::Hello Again All, :: I tested the 1J6 on my SECO model 107 tube tester and it tests very very weak. It's maybe up to 3%. But I don't have another one to try. So I have to order one. :: It WAS playing ok last night, so I suspect that one of the old resistors failed. Also I see 210 volts on each plate. Is that too high? :: ::Thanks, :: ::Dave :::Hello All, ::: When I turned on the radio today it refuses to play loud. The sound is good but if you try to turn it up it distorts but won't get loud. All B+ voltages are good. Where should I look? I replaced all paper and electrolytic capacitors. Nothing is touching that shouldn't. This is very odd. It would be odd that the 1J6 is failing. ::: ::: Please help if you can. ::: :::Thanks, ::: :::Dave ::: :: :: : :
