TELEQUIPMENT D31

Released 1960
11 Valves
Dual trace 3" green screen CRT with ?kV EHT
~5 MHz Bandwidth.
Original cost unknown.

NOTES	This was the second oscilloscope in Telequipment's "Serviscope" range, released two years after the single-trace S31. Aimed at basic servicing where 100mV/cm sensitivity and a 1uS/cm timebase are sufficient, the only feature is the inclusion of TV video sync triggering.
SERVICE DATA	You can download a copy of the manual plus a number of the plug-in units from the service data page.
CURRENT STATE	In reasonably good condition. If I could get past all the junk in the workshop I'd have tried switching it on.
WHERE FOUND	Another donation from Allan.

Some signs of previous work - the yellow caps probably aren't original,
plus the off replacement electrolytic, but it all seems sensibly done.

Note the octal rectifier valve (upper-left), a bit of a
suprise to find in such a relatively modern scope.
