WARNING

Valve equipment uses high voltages. Most early mains radios and televisions have a live chassis, so be bloody careful. I use an isolating transformer which not only helps to protect me but is necessary if you're going to connect earthed test gear to the chassis of the equipment. If you don't have an isolating transformer, make sure that the chassis is connected to the mains neutral. Don't go killing yourself, you might regret it later.

This recent addition to the shack is about the same age as me - fifty-five years old. However, it's in pretty good condition and works well. I would have liked one of the big Avo testers but, at around eight-hundred pounds, I don't think so. The Taylor cost me one-hundred pounds. You think that's a lot of money for this old piece of gear? Check out the second hand market and you'll discover that I did pretty well.
