  • Released circa 1960 ???
  • AC Millivolt Meter
  • Six valves (four EF95's, ECF80 plus EL90)
  • Original cost unknown.
NOTES Can someone explain to me how a simple millivolt meter requires _SIX_ valves ? I've seen 'scopes withe less !
SERVICE DATA Nope :-(
CURRENT STATE Owch ! The fronts a wee bit broke (guess it happened when it hit the skip) ; the bits seem all there but more difficult to fix is the soldering-iron-melted hole, curtosy no doubt of some bored dim-wit student.
WHERE FOUND Another refugee from a skip (cheers Dave)
