In January, 1999, a group of collector-historians interested in the use, history, and preservation of electron tubes and electron tube technology formed the Tube Collectors Association (TCA).
The Tube Collectors Association was established to support and encourage the collection of electron tubes of all types and historical periods.
TCA has an email reflector, open to all. It is a handy way to identify "mystery tubes" and communicate with other Collector-historians. To join, simply send a blank, untitled email to:
