Hey: Gang.
I'm really stuped with this Cobra 139xlr I'm working on.
I recapped the entire radio including the tantalum & electrolytic capacitors. I also replaced the four 2sc1419 regulators with new ones.
The radio will only put out 1 w on AM & 3 w on SSB.
I replaced the 2sc1306 driver & 2sc1307 final with new old stock ones I had, same issue still.
I even replaced the pre driver 2sc1973, issue still exists.
I even installed a new relay, did not solve the issue.
I even replaced the two bias diodes that attach to the driver & final, did not help.
I'm totally stumped.
Any suggestions guys as I'm pulling my hair out with this radio.
Thanks in advance.
