Heathkit introduced their first tube tester model (TC-1) in 1948. The TC-1 is an emission tester and was so successful, the identical testing platform was used in all their additional models except the TT-1. The differences in the 5 subsequent emission testing models are only mechanical and cosmetic. The only electrical difference was the addition of a leakage test switch beginning with the TC-3. The TC-3 also introduced new roll chart mechanism that prevented back lashing and binding of the roll-chart, this same, excellent new alteration was used in the rest of Heathkit's emission testing models.

Newer sockets were added as well the addition of more lever switch positions to accommodate the newer tubes types that were introduced in the 1970s such as compactrons, Magnovals and Nuvistors.

One other mentionable, models TC-1 & TC-2 had a socket for testing the (rather rare) 5 pin "Hytron "Bantam Jr." tubes. That socket was removed starting with model TC-3. Some of you have undoubtedly wondered what that small 5 pin socket was for and now you know. Ever seen one of these tubes or a radio that uses them?"
