Bought this from someone on SBAF a long while ago. Comes with a bunch of these little pencil tubes. Does not come with batteries. I will look and see if I have the original pot and knob. Upgraded Solen output caps. You can look on the Bottlehead site for the deets. Free to good home. You just pay shipping, shouldn't be more than $20 to CONUS. Or if you're in Chicagoland you can drop by and nab it.
