Reliable Tubes - Pioneered by Chatham
Offering the utmost in electronic tube dependability,
these Reliable types are a product of Chatham research
and development. Today, the Chatham line of Reliable
Tubes is an industry standard for both military and
commercial tube applications. For complete information
consult the new Chatham Bulletins available on request.
Engineering Service for Special Requirements
Where unusual requirements indicate the use of special
purpose tubes, these can be designed and produced to
your specifications. Chatham's Tube Division is
equipped to handle both large or small production runs
efficiently and economically. Chatham engineers are
available for special tube problems.
