Despite the inroads of transistors, there
are still applications where vacuum tubes
work best. Due to the specialized nature of
vacuum tubes and the limited exposure of
engineers and operators to them in todays
transistorized and integrated
circuit world, Econco has prepared this
booklet. The
information contained is a result of our
twenty-five years of rebuilding tubes and
talking with you, the users. We hope it
helps you in working with these products. If
this booklet
proves helpful to tube users, it is our
intention to periodically update the
information. Your comments and suggestions
would be appreciated.
