Hi Guys, I was looking at the schematic for the Heath SB-style 6-meter receiving converter, & saw that it uses a dual-triode 6DJ8 tube... Why in the world would this seemingly simple tube command the high prices that it (apparently) does on eBay...? Is it yet another in a series of "...audiophile gems", or what...? ~73~ de Eddy VE3CUI - VE3XZ
