[R-390] Variacs and solas: additional thoughts

[Bob Camp]

Hi

For a whopping $10 Radio Shack will sell you a three amp 12 volt  
center tapped filament transformer. The nice thing about the center  
tap is that it will give you both a 5% and a 10% adjustment off of a  
nominal 120 volt line. Three amps is enough to run any radio in the  
R390 size range.

Given that the radio works better off of a high line voltage it's not  
real clear weather you should spend the $10 or not. As mentioned in  
the previous thread using a fuse or two is probably a good idea.

     Take Care
