Replaces the 80B (A2) power supply
- need extra mountings as it is smaller compared to the original
- poti for 5V adjustment up to 5,2Volt ( up to 6,3V by changing R3 to 1,2K )
- LEDs for easy control of 12V and 5V presence
- test points for 5V,12V and GND
Note: This power supply can supply 3A in maximum, where the original power supply can supply up to 5A. However during my tests I measured 1,5A in maximum within a SYS80B game, so the 3A of PSY80B should be sufficient.
