Hi Nate! 

Just a couple of quick thoughts to ponder: 

1. How do you plan to tap an insulated primary? 
2. Your Variac is rated for ~ 550 W power, your two trannies will draw at 
least 720 W. 
How do you plan to cool your Variac? 
3. With a 10 amp fuse protecting a 3.75amp Variac, won't the Variac smoke to 
protect the fuse?  I have 15-Amp fuse protection on a 20-Amp rated Variac to 
an NST that should only draw 8.35Amps Max, but where I live fuses are much 
cheaper than Variacs.
