[sdiy] vacuum tubes!!!

[Michael Ruberto]

well shoot, now I have more projects ;)
I got 6 of the 8417 is it enough for a nice amp? ;-)

damn and I recently passed up an auction for military tube testers. there 
were 10 of them in the lot and I thought what the heck will I do with 10 
tube testers? DOH!
