    oh and a shed load of tr*ns*st*rs that I
    couldn't be arsed to count.
  • Dual Trace
  • Green screen storage C.R.T.
  • Bandwidth unknown but the timebase only goes
    up to 1uS/division !?
NOTES

 

It seems that Tektronix, keen to ensure the longevity of their 'scopes, fitted a number of special traps to catch parasites before they could do further damage. Here's a picture of just such a parasite, with all three of it's legs caught in one of those traps. Picture of parasite caught in a trap [7K]
SERVICE DATA Nope :-(
CURRENT STATE A little battle scarred on the outside but mint on the inside.
WHERE FOUND A donation from "Dave".
   

Chassis view of 3A1 dual trace amplifier [25K]
Type 3A1 dual trace amplifier. Incidently, the little cylinders, bottom right,
aren't parasites, they are miniature "Nuvister" valves ; Tektronix seemed to
use them by the bucket load in a large number of their products, yet I
can't recall seeing them used anywhere else.
Chassis view of 2B67 timebase unit [26K]

The 2B67 timebase plug-in. As with many scopes of the period, whilst
tr*ns*st*rs were appearing in larger and larger numbers you often
find the timebases are still heavilly valve based.

As with all Tektronix scopes, the build quality is awesome.
