[Shop-talk] Power supply noise?

[Steven Trovato]

Messing around inside a brand new power supply wouldn't be my first 
choice.  Try to get it further away from you.  I don't know what your 
room is like, but is there a closet or something nearby?  My 
father-in-law likes to use a 12 Volt car battery and a 
charger/maintainer like a Battery Minder.  The battery provides 
plenty of current and the whole thing is completely silent.  You also 
get to use your radio in a power failure.
