emerson 557 ?
#10

Finally with the Holidays over and the deep freeze fading I got the replacement tubes put the diode in place of the selenium rectifier and powered up the set .21amps draw. FM works but I get nothing on AM other than static except for about 5sec it played then went to static a couple of times. Unfortunately the print off Nostalgia leaves a lot to be desired as to resistor and cap values and the colors on the resistors have faded so some are hard to read I don't have vol 19 so I'm working on getting a better print. I did the voltage readings and almost all are within 15% with the following exceptions. See attachment, which I hope come out

Not sure where to look next I have been looking for extra grounds and shorts, have retested tubes all for not... Any Ideas on what areas to concentrate on?
