Im still having issues with my ARIII. Ive replaced all of the large caps and a few resistors as well. Even one of the transistors on the heat sink. Basically, Im at a loss for where else to check on the board for what is causing my PB to not get enough power. Does anyone fix these on here?

If the 5 volts are low, most likely the LM 305AH is bad.
 
ive called like 10 places for this part, and alot of them have it, but i have to place a minimum order of at least $50! One had a min. of $500. I finally found a place that would sell me one. ElectronicsPlus. thank the lord.
