FM Towns:Tower Power Supply Repair and Capacitor list

The Generation 1 Power Supply


This power supply is not known to be a tremendous source of pain to maintain.

The Generation 2/3/4 Power Supply


Very well known and the pain these cause is also well known. This PSU card is sideways and not flat like the Gen1 card. As a result of this, the acid leaks sideways down the card and destroys a lot of resistors, the relay, etc. It is uncommon to clean, recap, and then the PSU card dies months later. Hearing a whining sound when the computer is plugged in and not turned on is an indicator that the capacitor near the black relay has leaked badly.
