Default Re: Telequipment D75 scope.

Yes, that is the kit. The early versions were TQ D75. Later they became Tektronix. Various ones, could have been D751 thro to D755.The D83 was sold as a chassis plus vertical plug in plus sweep plug in. For D75 models, you bought a complete unit. Obviously the plug ins were removable and could be changed, but the factory only supplied as a complete scope to a specification which could be specified by customer. (my understanding anyway)
The "kit" was not present on any earlier models (D65 thro D67, D(M)63, D75, D83 and many others. Later they became standard, with retro fit kits available.
That type of voltage selector panel was common to all (most anyway) of TQ scope production from the early S31 onwards.
From the D75 series, the D755 is the most common because they were a forces specification, and were "manufactured and supported" after general production finished as I understand it. Often two different phosphors, yellow and blue predominant
