Wax nostalgic about and learn from the history of early electronics. See articles from Radio & Television News, published 1919-1959. All copyrights hereby acknowledged.

The Triplett Electric Instrument Company has been in continuous operation since 1904, although today it goes by the name Triplett Test Equipment & Tools. It was founded in 1904 in Bluffton, Ohio, by Ray L. Triplett. Mr. Triplett is holding his company's first vacuum tube tester, the Readrite Model 201, which debuted in 1921, in this full-page advertisement that appeared in a 1954 issue of Radio & Television News magazine. Triplett claims it is the first commercial tube tester. A pretty extensive search did not turn up any photos of the Model 201 tube tester, but there is a follow-on Model 215 tube tester on Steven Johnson's  Readrite & Triplett history webpage. Here, too, is a very informative page outlining Triplett's history, including a picture of the "portable" ammeter built into a pocket watch case. The "new" Model 3423 Mutual Conductance Tube Tester, priced at $199.50 in 1954, is the equivalent of $1,901.50 in today's money (per the BLS Inflation Calculator).

50 Years of Setting Standards

Ray L. Triplett with the first commercial tube tester - a Triplett production - and Triplett Model 3423, the leading tube tester of today and tomorrow. See it at your parts jobber Model 3423 Mutual Conductance Tube Tester. Dealer's net $199.50

The only tube tester designed with 50 years experience. Two important lesson are learned, from experience, by the manufacturer of test equipment. First, the value of test equipment to a service man is in direct proportion as it reduces his necessary labor and increases his profit for the same span of work time. Model 3423 will give you no false readings to waste time - the patented circuit for tube testing employs actual signal (4 kc) for grid signal. It also has a complete coverage of all tube types - sic plate voltages (including 0-10 variable). Micromhos scales read 0-1800, 0-6,000, 0-18,000 and 0-36,000.

Secondly, test equipment costs money and the purchase must be protected against quick obsolescence. In Model 3423 the multiple switches allow making any combination of tube connections and is protection against soch obsolescence.

Ask your jobber to demonstrate the many other extra features of this tester.

Only Triplett offers you a ten day free trial on all test equipment.

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
