All,

What is the recommended grid-gnd circuit?? The original sb-220 had an LC network; it seems to be a common recommendation to replace the coil with a 33 OHM resister. Are the caps changed as well??

Thanks,
Dan

Need some Elmering.

Can anyone explain why the Harbach Suppressor kits use Ceramic Disc instead of Dipped silver micas for Rf choke replacements?
