Power Supply K7203

I have just built the K7203 power supply. Put on volmeter and it read 3.2v on output but then it blew the 3a fuse on the ac transformer I had connected to it. I hadn’t connected it to a load so am unsure why the kit blew the fuse. Can anyone help?

Sounds like you have short.
Could you post clear pictures of the top and bottom of the kit?

I’ll post pictures of both sides. so it ended up working buy just for a while. it fused the 3a inline fuse again. I also noticed that it delivered constant 30v output and the 10k potentiometer which I have put in place of the trimmer didn’t have any effect. thanks

can’t seem to be able to upload…
do you have an email address that I can send direct to?
