[Tubejunke]

I don't have the set anymore, but I seem to remember many 6AU6 tubes in there along with a few of the others mentioned. I thought that the 6BC5 was called the "reactance" tube, but it's been about a decade. I may still have the schematic somewhere around here. I tend to think whenever I have seen hand written tube #s that some sort of upgrade or modification was done and that was the techs way of noting that for other techs. Great set though, especially if you like em heavy. The power transformer alone probably weighs 20 lbs!
