Re: Jerrys Power Supply.pdf

Can you recommend a type of fuse to use on this power supply?
I know this sounds like a rookie question, But hey,
I'm a rookie. (At least I'm honest :) )

I'm ordering the transformers from MPJA,
the Capacitor from digikey,
and will probably get the bridge locally.
( digikey is out of stock on this item )

I guess I will go with a gecko for this project unless
anyone has a better idea.

Thanks for all the help.
