first off it has no transmit or recieve then when you key the radio up the tx indicator pops up on the front but the bars dont move and your voice comes throught the radio speaker and when you unkey there is know roger beep and yes the beep is on i have checked the regulators on the side there are soldered good and they have the right voltage the audio chip has the right voltage the finals have 2 volts less than what it sould have but that could be dew to a sorry volt checker but that aint know reason for the outher stuff i have channged the finals and put new ones in it and there is a regulator behind the four knobs on the main board that gets so hot you cant touch it but it has the voltage it sould have and someone else told me that that one is post to get hot because all the heat sink its got is the board which there right also when you turn the radio on the bars on front dont move for the recieve if you need to know more please ask me because iam up nee deep in this thing i want to get it fixed so if you can help me techs please help i thank you very much my email if you need it to ask me something sidewinder107@alltel.net

Sidewinder,i don't know how to repair it but know what happened.They put covers on RFamps for a number of reasons,one to keep stray RF contained,to prevent RF burns,and to keep us mike jockeys from zapping our rigs and ourselves.On tube amps there's a corona that forms on the surface of the power tube during tx,producing a static charge which can be quite large.Tube amps also have a hot chassis tens of volts hotter than anything in your radio.It may cost more than it's worth to repair.
