I thought I had just bought one of these. The box was WAY heavier than expected... Yeah, there's 10 in all! Lots of experiments coming soon! A roughly 8-10 watt 5881 version is up first. Also going to try a reduced voltage Tung Sol 6V6. A 10" combo with a vintage '69 CTS that I have, or a maybe a WGS Veteran 10.
