Hi All, Can't keep my hands off those glowing things, just completed a tuneable Pre-selector for 136-138kHz with 300Hz bandwidth, uses two 12AT7's. Could have used Fet's I guess but valves more fun and anyway my fingers too arthritic these days. Dont forget valves bite (only twice this time, but! ) and off the shelf box's don't have enough ventillation slots these days, valves get hot!!! 73 Laurie.
