[time-nuts] HP5061B Beam Tubes

[paul swed]

Yes the Cs are long evaporated. In my frankenstein 5060/5061. I built a new
oven controller to cook out the remains. It worked as the system locks and
I get 2nd harmonic etc. But we are seriously speaking of fumes.
It was bit of fun and it didn't really matter that I was hacking. The 5061
was a $125 flea market special.
The 5060 tube was given to me from a fellow time nut and was believed dead.
Well its seriously on the last fumes.
I do the same thing as above. Fire it up every qtr. See that its still
works, marvel that it locks and shut it down after 48 hours.
