Smallest RF-quiet wall wart?
 

I am looking for a small travel wall wart (power supply) that converts
120VAC to 12VDC.

My Rat Shack supplies are very "noisy" when used with my R10 -- lotsa
60 cycle interference. My big shack supplies (Astron) are quiet but
too big.

This one looks pretty good:

It would be nice if the prongs folded down, though.

Any recommendations?

I doubt the supply itself is the source of noise- it i simply conducting
noise from the AC mains to your receiver. Try winding the DC leg on #43
toroids to choke off any RF along the line.
