If you just want to check operating voltages or eyeball things, a VCR signal is as good as any. To adjust things like linearity & centering, it's better to use a pattern generator that will give you a crosshatch pattern, cross, dots, etc. B & K made some Dynascan generators (1230, 1245, etc.) that are small enough to hold in your hand and often sell very cheap on eBay. Search for "color generator" or "pattern generator." For test gear like this, I'd generally avoid a vintage device, which will need the same kind of service as any old tube equipment and may also need calibration that you're not equipped for.
