I'm working on a Bally 6803 display that has the H & J segments out on all digits. I've re-flowed the solder and confirmed it's not a cable issue, so I'm going to swap out the resistors and transistor. I'm having a bit of trouble finding an MPSA42, but Marco lists a 5A-9216 - I assume as a recommended swap. Before I do this and blow something up, I thought I would verify. I can't find much out of the web that shows these are equivalent. Can anyone confirm I can swap these? Looking at the specs on both, I think I am fine, but I'm far from an expert in this field.
