Ok, I got the ammeter working. I deleted a bunch of crap because it was a wild goose chase based on a bad solder joint on a capacitor and some loose crap
(I almost wrote bad transformer socket! for some reason, wow I am agitated, this does not have a transformer socket on it, I just started imagining words ).
I don't know the exact problem but I think I basically swapped a transistor on one of the PCB now when I measured them all, so the A2 board has all of the power resistors go on fire, but I got it working by overrating the fuse by 300%. At least the transformer voltages are normal, the rectified voltages are normal, hopefully at this point I just need to swap some transistors and maybe it will work. Have not ran it for more then 3 seconds like that.
yep, swapped a transistor. works fine, bit a buzz at full power unfortunately even with all the work, but at least the ammeter works. Problem was mostly a capacitor that via got dissolved making the -45V rail go screwy (everything from oscillation in certain output voltages to the ammeter causing the rails to change. problem was that I replaced a 5 lead cap with a 2 lead cap and one of the vias cracked, at least I think there was a via there, because the screw terminal capacitor has one.
Maybe it will stop rattling when i replace a few screws but god damn that is a load off my chest, hoorah. buncha crap is still loose. (only at max power).
what a fucking beast though, survived swapped cards in wrong polarity, swapped transistors, a missing power rail and only some resistors got hot when I upped the fuse by 300% to run it on overload for trouble shooting purposes. if it passes after the damages
incurred by the insane repair man, its a fine instrument. I wanna see this thing go up against starfish prime lol
