just a little update I have checked all of the transistors on the 702 board with the diode setting in my trusty radio shack multimeter and they all check out (no weird diode readings at C E junctions)
already replaced the electro caps, two ceramic caps tested dead on
testing the diodes now but so far so good (can't tell if it's just corrosion on the leads but it can be a pain to get a reading.... it love to just swap them all out with something not made of unobtanium/aka in my parts bin)
winding down for the night but we shall revisit this probably Wednesday
