<I really appreciated the Amp Supply tuned
input I put in the 4-1000A amp I made back
in the 90's. It was pure simplicity and
worked so well. I put one in a SB-220 as
well with the same wonderful results.

##  I believe the amp supply tuned input board used arco compression
caps for both C1 + C2..and a fixed torroid for the coil. The arco compression caps were padded on 160m. I think the biggest arco I have is aprx 1600 pf. They ranged from 200 pf up to aprx 1600 pf. Arcos have a limited min-max range, which is still ample for any tuned input. Typ would be like 200-500 pf etc.
##  It was ideal for folks with HB amps, and anything else.  Just tweak 
both caps
for flat swr, then repeat for each band.

** On the higher bands there was plenty of room to tweak the coil spacing which helped to balance 15/17 and 10/12 VSWR along with the variable caps.
