Took the back off today for a peek inside.  Uses one 12AX7, a selenium rectifier and a D cell battery for the ohms.  Looks pretty rough.  Think its too far gone for a restoration unless I can find a new cabinet.  There's actually three sections to the bakelite cabinet.  The middle bakelite section is the one thats messed up.  

As far as the input jacks, I'd probably end up changing them to BNCs.  Keep the old jacks in a small plastic bag tucked inside the VTVM in case a future owner wanted to change it back to original.  

If you look closely, you'll see a date of October 20, 1961 stamped in three places.  I could swear it was much older. 

The more I look at this thing, the more I lean toward giving it away and let someone else have the joy of restoring it.
