S-120 has 4 toobz 12BE6 pentagrid VFO/converter 12BA6 pentode IF amp with regeneration (erzatz BFO) 12AV6 dual diode triode detector and first audio/AGC 50C5 audio power. Can copy CW tolerably on 160 and 80. Get over to the glowbugs(google knows about it) mailing list and ask what you can do. You'll end up having to build something though :-) 73, -Bob
