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.

The Advance signal generator covers 30kHz to 30mHz, and is ideal for vintage valve and transistor radio alignment.
