A regulated screen supply for an 8171. takes a approx. 1200v, 100mA power 
transformer, rectifiers, C-filter, a 723 IC, a hexfet, a SCR and a few 
small components.    This takes perhaps $35 for swap-meet mavens   The 
0mA  grid bias supply might cost  $25.

The DAFs I am familiar with ran substantial grid-current.  Perhsps 1db 
more power resulted  -  compared to virtually zero grid-current 
operation.

The only tubes that are simply not suited for use in a DAF amplifier are 
those that  are producing embarrassing splatter.

It's kinda like voting for Ross Perot.

I realize that it sounds off the wall, but I am beginning to suspect that 
some of the true-believers may have had trouble with an authority figure 
during their early childhoods.  For some, the 3/2-Power Law seemingly 
sticks in their craw.  
I also suspect that some of the professed True-believers are covertly 
seeking attention.  

Cheers, Phil.
