<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.
