I'm looking to build a 160/80m rf deck. I have 4-5kv available at 1-2A What tubes are "easier" than others down there. Does the YC156 lend its sell to two band operation at LF? Any pointers to what tubes to be on the look out for and possible designs out there appreciated. Again I'm look at just 160/80m. Thanks and HNY. Neil G0JHC
