[Amps] SB220 QSK bias and RF relay mounting

If it works OK, then go with it as you have it. If the relays don't seem 
to pull in quickly, might consider getting the relay coils out of the 
immediate AC magnetic field of the chokes (60 Hz) and move it to the 
other lower screw. It means adding a length of copper bus wire from the 
output loading cap over to the contact, but that won't be long.

You can get wider aluminum angle stock at most good hardware stores so 
you are not stuck with the existing piece for the two relays if you have 
a set of sharp drills. I guess that relay hole is large diameter though...
