I am rebuilding an SB220. Harbach Electronics has been out of its parasitic suppressor kit for some time now. Anybody know of anyone else who makes this suppressor or has plans so I could build my own?
 

I used some 1/2" brass strips and built my own parasitic choke. I used 2 100ohm, 3W metal oxide and ran in parallel. Then made a horseshoe so to speak and made it about 2" long. About an inch apart spacing so you can fit resistors between ends. Seemed to work great for me.
