Re: Trannies For Dual Rec?
Hi rich!  
 
You better look at the 1650T rather than the R,For a hundred watter,priZ of 1900 instead of 5000 omhs.That's for four valves.  
 
Which means,460V(B+):by 1900 omhs=0.242 amps.  
 
242 mA.Which means that the 373's are too small.Closest from Hamond would be the 300BX,400V ct.You would have to lower it a bit!Zenner trick!  
 
 
 
Best regards.  
 
Max.
