The Alpha 70/70V and 77 series were built that way and a few other brands I 
dont remember right now. Possibly Henry. I did it that way for 30 years on a 
HB 2M 1500W amp until I actually drew out the circuit when I wanted to 
repackage it into something smaller. It is very easy to make that mistake 
and it never affected me....BUT?
