I agree with Tab, but don't forget the safety items - Isolation transformer and a variac. I use both on every single radio I work on.

The expense of technical equipment seems like a lot, but remember - you will use these items on every radio. These tools will last forever too. Once you buy them, you are set up for a long time. Get good ones and learn how to use them. Instead of buying more radios, start buying these items.
