Anyone have any info on a stud-mounted power rectifier type TR100? Possibly International Rectifier from around 1966.
There are 4 making up a bridge rectifier in an ADT power supply, which I modified in 1976 as a car battery charger. The circuit includes 8 x OC28 in parallel on 4 heatsinks (12.5 x 18 cm). Max rating for an OC28 is 37w.
The electrolytics (3 x 8000 uF/50v) have leaked (not too surprising as they are dated April 1967!), and the supply no longer outputs 12v.
