Hi everyone,
Just wanted to share a success story that might be of interest:
Our MAS II was repeatedly blowing fuses, which we traced to a failing power
supply unit. The original PSU (Cosel LEA50F-30Y) has been discontinued, but
we were able to replace it with a PMT-30V50W2BA.
Our electronics technician, Marcel van Helden, handled the replacement and
put together a short guide, which I’ve attached in case anyone’s curious
about what we did.
Best,
Sameer
