another update ... 40w suply worked ok, the short time it was installed.... and will keep as a backup :)

Fitted the 60w PSU that arrived yesterday ... very impressed with it ... fro Cole-Tech ... ordered fri, arrived Mon, and looks like a decent bit of kit ! :)

1st test output 25 odd mA ... so had to reduce output to 63% to get a safe 20mA (Which I guess , in theory is the max I should push through ? )

done several hours with it so far ... it's cutting approx 40% faster than the original PSU (but I didn't have a mA meter hooked up) ... so all goo so far :)

all happy here :)
