Recommendation:If you are a hobbyist or professional looking for a high-quality transistor tester with extensive functionality and a hands-on assembly experience, the Heathkit IT-27 Transistor Tester is a great choice. However, if you are looking for a more portable or budget-friendly option, there are other testers available on the market that may better meet your needs.
To use this tester, one first performed a leakage test the meter should not move upscale by very much or at all. Note that the feet needs to be re-glued in place. I checked both germanium silicon transistors as well diodes, confirming this tester is working.
I also tested one power transistor. According to the manual, satisfactory transistor gain may be assumed if meter indication increases one division or more above leakage.
This is a compact ruggedly-build tester, designed to be included in ones tool kit. Up for sale is an IT-27 Heathkit transistor tester in good working condition.
To make it ready for this listing, I first check all solder connections. Next, I used exit to clean all switch contacts, transistor socket and the banana plugs jacks. I also cleaned the battery contacts. According to operational notes in the Heathkit manual, testing is performed on a qualitative rather than quantities basis.
Next, the mode switch is moved to gain position. Thus, this tester is designed to be of a go-no go basis.
