I've been using EZSBC's PSU5 on Bally/Stern solenoid driver boards to replace LM323K's. They work great. The only caveat is that you'll need to jumper over the resistor (R50 - 4.7ohm) that Bally/Stern used to offset the 5V slightly to account for voltage drop (5.25V or there abouts). The PSU5 will oscillate and not function properly without the case tied directly to ground.
You can even remove the large heatsink - the PSU5 won't need it.
