Hey All!

Got one of these on-sale-specials from RadioShack... the 70v line
transformer... got the 4-ohm secondary connected to an appropriate speaker.
 Which tap do I use for the primary?  They're not marked in impedance...
they're marked at 0.62w, 1.25w, 2.5w, 5w, and 10w...  

For 600-ohms (er, 500ish) Do I use 0.62w?

Cheers/73!
DK  :-)
