What leads should be used with old Heathkit tube voltmeter?

[Thyratron]

I wasn't quite sure on which board I should ask this, but since I think these meters still get some fair use in old TV work, I'll try here. Recently I found a Heathkit V-7A in nice shape (and with the added bonus of a Mullard 12AU7 in it), but missing its leads. This is the one that has the banana-plug sockets for the common and AC connections, and the 1/4 inch "headphone" socket for the DC. Can I just use any everyday leads, or do I need something in particular? Also, what type of lead should be used in the (unusual) DC jack?
