What are the differences between the Hickok 539B and the 539C tube testers?

Apr 20, 2008 by Tina | Posted in Other - Electronics

Do they have the same manuals and calibration procdures?

The two units are when all is said identical. the 539-C replaced the older one in the early sixties. The two lowest ranges on the micromho r were deleted. provision was added for testing nuvistors, those tiny metal-ceramic tubes hardened in FM front ends. A couple of styling changes were made to the meter cases. Oh, the price went from $392.95 to $485.00. The running of the two instruments is identical. One of the best tube testers ever made.

How do I read an anti-freeze tester tube for my car?

Sep 06, 2008 by Andrea C | Posted in Maintenance & Repairs

I have an anti-drive away tester tube containing a blue, red, orange, pink and green ball. Which color means what? How do I present it? I had the packaging for it that explained all this but it got thrown away.

downhearted is the best color...
