General Electric516F USA import. It may be of interest to fellow enthustists How I fix this radio .Firstly I 

-see if any previous work done. I replaced the tubes with a set of good tubes for testing .I don't switch on just yet. I check for shorts and the filter condenser capacitance ( was over 50uf ) -that was fine .I reform the condenser from 26mA to 0.5mA This may be done by placing the condenser in series with two 15-watt electric lamps(series connected) and a DC supply.When first connected the lamps will probably light ,after some time will cease to glow.I like to have a meter set to mA to see progress.Next job switch on Dead -mains switch open circuit I solder a wire link( for testing) -still dead -My mistake it is a clock radio I removed the clock at the beginning . The radio now works well. I don.t change resistors or condensers only, if I have to . I do check coupling condensers -That's it.

To thank the Author because you find the post helpful or well done.
