Re: Output Transformer for Spitfire
You know, sometimes I miss the obvious  
right in front of my face...I'll try the  
speaker cabinet on a different tap. I don't  
have a 4 ohm cab, so I'll have to run the  
8 ohm cab on the 16 ohm tap. A small amount  
of rewiring required, but no big deal.  
 
This is a Class A amplifier running about  
100ma of bias current. It is possible that  
I'm experiencing a core saturation problem.  
My B+ is also running about 350V - driving those EL84's pretty hard, but they don't  
glow...  
 
Anyway, I'll do the experiment tonight and  
see what happens.
