no sorry im not that far advanced

pre65 wrote:What size resistor were you trying ?

1r 12watt.. brings the 10.2 volt down to 9.2 BUT 9 volt useing a variac
its fine

i have tried that but it stops the module working,, poss it does not like resisted load can only get 5.5 volts out

same prob here ! 3 off ecc83 240-9volt 30va transformer.. trans is fine but 10 volt... after 2 hours starts to get hot at 55 deg then it seems to get hotter more quickly at 60 the legs of the 3 leg thingy are at 70deg at that point the AC in the the dc starts to go up... on a variac at 216 ac i get ...

any recomended type and supplier

prob depends on what type. engineers/metal workers is not far off the temp of braizing rods

i still use lead/tin i have some lead free/silver solder (maplins) dont get on with it at all

o.o47uf seems to be recomended, pm me if you want some (due to a cock up i have to many)
