Hi all, I am currently working on the cpu board. I have a locked on coil and one not working. I will be shotgunning it, I'll be replacing the 123ap transistors the tip 3055 transistors the 270 ohm resistors. I need to repace the diodes as well. The number I have on the diode is BA2C5 will a 1N4004 work in it's place? Any help much appreciated.
