Still going on today. Admission = $10.
Among 10 or so other finds, I got the following:
Two 1950s GE 6SN7GTB, test strong - $5 each - there were more 6SN7s, some test new ($10) & some close to new ($5).
One NOS 1950s Sylvania 6SN7GTB - $5
Four NOS 6AU6 - $2 TO $3 each.
I know there are more NOS 6AU6s, if anyone needs them I'm 10 minutes from the Fest.
