One way is to use a socket adapter that provides some contacts on the topside of the chassis for you to connect your voltmeter leads to. Sometimes these show up on ebay. This image was cut from a page on the RadiolaGuy.com page who also may have some available for sale.

The other is to turn the chassis on its side so you can get at the bottom of the tube sockets to connect the voltmeter lead to the proper pin. Of course this involves accessing the chassis while its powered up so you need to be extremely careful. I usually make the voltmeter connections first then power the set up.
