[Boatanchors] 19, 30 & 31 tube info

[J. Forster]

**  Opinion  **

Rather than use relatively scarce really old tubes for things like scout
projects, why not use more modern, common parts?

Years ago I almost puked when a load of Tektronix scopes went to a "trade
school" for kids to learn how to use a soldering iron.

UTTER WASTE!

YMMV,
