[Heathkit] Heathkit "SB" Series I.F. Filters

[Eddy Swynar]

Hi Guys,

Awhile back there was interest expressed in how one goes about homebrewing a wideband AM filter for the SB-300 / 301 receiver...

By rummaging around the internet, I managed to find the original description of how one goes about doing this---complete with schematic diagrams---which I received from a former Heathkit engineer...

If you'd like a copy (4 pages in total), drop me a line---I'll send them along as jpeg attachments (I only hope this Apple iMac will be compatible with your Microsoft system, assuming that's what you're using! Hi). Years ago I built an SB-310 wide-band AM "clone" along these lines that I'm VERY happy with...
