Question about Radio Communications
This transceiver is a moody *****.I did my best to look for any cold solder joints,power supply is reading 13.5 volts dc.the radio always lights up,but sometimes does not trans or receive,next day it could work fine....While I got your attention,I also have a old tube radio that popped 2 oil caps,a.1uf and a .047uf 600w v made by Atlas,they shot the foil out,is there a modern equivilant replacement? The radio is a Robyn T-123B.Thanks,Brozinski.
Might be worth checking the microphone cable on the transceiver, specially near the plug, or the push to talk switch. I saw this umpteen years ago with a CB that was intermittent.
High voltage capacitors are a bit hard to find but look on the net for vintage radio suppliers. While you have the tube radio open, look for resistors that gone high, this can put higher voltages than design on the caps and of course can quickly wreck tubes that were otherwise OK.
