I don't mind making up/solder my own bridge just a matter of I've no idea on how to do it yet lol. I've actually got a good temp controlled soldering station and also a nice portable gas unit with all sorts of tip that is very good to use (what I use normally). The ac stepping transformer my father-in-law bought is the 105va unit, mine I think was 300va or so from memory, both are same brand/ac type just different sizes.
May I ask, what's the difference in va to watts or what's va stand for?
Yeah a 4700uF 16V cap, but think a 25v was suggested as better option
