    Hello..I have a ts 440 that i was making a minor repair on the RF Unit and the problem was No rx..Well i found the issue and i Made a boo boo and shorted out a trace that leads to pin 6 on J-1 on the RF unit..Now i have the dreaded dots..I think that line is supposed to be 8 Volts..I think this voltage may come from the control unit but not sure..I heard a snap but cant find the damaged part.Radio comes on fine But i have lost this voltage somewhere Thanks in advance for any help
