    accelerator anode. Odd? 
 My father had some ham radio related device with a one inch CRT in it. That basically
looked like a 6L6 with a white top ? including having an octal socket (8 pins).  That?s
even harder than the device you described. 
 
 That sounds like a Station Monitor... 
 
I think so.  Home made variant of the Millen monitor Will mentioned, I believe.
