Hello - I am looking for a simple solution to use my old blue transformers to convert the 17VAC (yellow and brown terminals) to DC - mainly to supply LED lighting and misc. accessories. I have multiple transformers so I could dedicate one per needed output voltage (ie. 3V, 6V and 12V). So I am looking for a schematic and parts list to built the required conversion. I realize it would be easier to just buy DC power supplies but I am hopping to re-purpose the good old transformers! Any help or suggestion are greatly appreciated! Thank you.

... and resisters to lower voltage to led level. No good shorts protection, so cheap dc supply sounds smarter (or old cell phone charger)
