and I'm feeling very much better.
2-week post-surgical exam says... no tub or swimming yet, but the mass from my knee is nonspecific and non-threatening.
this provided a chance again to stop in at Ax-Man and paw through the tube buckets. thought I found a couple decent 6EA8s. both had 8 volt Tubes From Hell in the boxes, lost that $5 bet. win some, lose some.
