Bought the rig as is and found that the previous owner had swapped power supply connectors going to the display board from the AVR board. On HV and HG were 9 volts AC and the F and FG were gnd and -34v respectively. When I first got tgevrig, the filament wires were glowing red and partial display were all lit . On the part of the display lit, all segments were displayed. Once I corrected the wiring , the display was only partially lit and still all segments, nothing intelligible . Power supply voltages are good to the board , not sure the filament voltage hitting DC circuit did any damage. Looking for any tips thanks
