On my SX-101A I notice it has an band marking for a converter for either the 6 or 2 meter band (as well as a converter spot on the band selector). I'd love to find a vacuum tube converter. What sort of converters are out there that will put out the 30-34.5 MC that the radio wants? I'd love to find something but I haven't a clue as to where to begin looking or who made them. Any ideas / suggestions?
