WHoever said ss stuff is better then em, well, i dont agree.
My 2 em pins have been perfect since shopped.. my ss bally freeedom, not so much..
rebuilt mpu. replaced a ton of connectors.. worked for awhile then shat trhe rectifiers ont he ps board. replaced those, worked then after awhile displays got real bright. found toasted regulator on the solenoid driver board.. fixed that, started getting lights that would stick on and some never worked, had to replace a bunch of transistors.. Then intermittently i would lose flippers due to the relay bieng intermittent. found bad greound between the boards and repaired.
then after all that mess, it worked for another year or so and now its dead again. No power to mpu, replaced rectifiers on the ps again and same.. i have no ac into one of the rectifiers, and form what i can tell i have a "odd" failure of the transformer itself.
Im not too suprised, the thing always ran hot.
SO if anyone has a early bally ss transformer with or without the rectifier board, lmk.
