   Thanks for the kind words, John. I have a few ideas in mind that I'll be   
   developing. First thing on the agenda in the tube world, though, is to update   
   my 813 based Matrix amp. It sounds great, and I get 60 watts per channel from   
   a pair of them. That    
   would be equivalent to 2 single ended stages. I mostly want to update the   
   filament supplies using one of Linear Technology boost buck regulators. Takes   
   in 9 to 70ish volts to produce 10 volts out at 90ish% efficiency. Will replace   
   a couple off the shelf    
   but accoustically noisy supplies due to their fans.   
      
   Otherwise its a dang nice amp...  simple lineup... 2x6GX7 and 2x813. It does   
   have 2 6AS7 and a couple 12AX7 for HV regulators.    
      
   Also need to update my p-p 801 harmonic equalizer amp. That likewise produces   
   60 watts per channel for a pair of 801s per channel. That's more than you're   
   supposed to get from 801s but the H.E. concept increases the dynamic range   
   that much.   
      
   Warmest regards,    
   Stephie
