i'm in the process of building the power supply and would like to know if thermal compound is used on the base of the rectifier and on the base of the capacitor. i don't know if it's advisable to mount these without it. i had a look online for paste but keep getting paste for cpu's .
will this do?

I mount the rectifier with thermal paste you don't use it on the caps. Paste for the cpu should be fine. ..Clive

i decided to test the coil with a power up so i used a safe block , hooked up the brown and blue to 230 vac i then joined black and yellow together and red and orange together on the secondary and put them in a terminal connector . when i engaged the safe block the coil hummed for about a second and then stopped. i checked the fuse in the safe block ( 13 amp ) and it was blown so i tried again and the same thing happened. i metered the connector and obviously got no reading . am i correct in thinking that i should not have blown the fuse and should have 50v ac across the terminals?

Do you have a link for the coil?

You need to connect the two sec. coils in series so join red and yellow and measure black and orange 50V It might well blow the fuse on start up with a 625w coil

just my luck to blow fuses. i thought i might have connected it wrong or perhaps i shouldn't have tested in in the manner in which i did. should i wait to get the rest of the supply hooked up or would that matter?

Ok short black and yellow together and take the output from red and orange then you should see 50V You have connected them in parallel . I think the fuse is blowing because of the surge. ..Clive
