The DC to DC converter identified as IC 18 DP-4 has been fried.
The display is dead and the PLL is off frequency.
According to the schematic, it takes in 13.8 volta and produces -10 volts for the PLL
and -18 for the display.
It also has two lines each labelled H going to the display.
Heater(s)? What voltage
Any help would be appreciated as the radio works otherwise and has plenty of room
