NOTES

A dual trace oscilloscope utilising plug-in units for the 'Y' amplifiers.

Apparently there are 102 valves in this thing ! Hell, there are 14 of 'em in just the power supply ! Yet its still lighter than the Cossor. Lined up in rows, hanging upside-down, valves everywhere ! And a ruddy great fan at the back trying to keep it all cool.

Click for larger view [38K[The scope was manufactured for a number of years, as illustrated by the April 1961 advert [138K] shown opposite. But check out the £600 price tag ! To put this into perspective, this represented half the yearly salery for a typical design engineer.

Whilst a manufacturing plant was set up in Guernsey (off the souther coast of Great Britain), I wonder just how much of the scope was manufactured there and how much was "simply" assembling modules built in the state ; these modules would no doubt be classed as components and I bet that dodged GB import taxes to some extent.

SERVICE DATA Yep. Scope came with original manuals. Even came with the original calibration record, dated 24th April 1957. You can download a copy of the manuals in .PDF format from the service data page.
CURRENT STATE Working.
WHERE FOUND Bought privately for £40 (including the scope's trolly stand) with some other bits 'n bobs thrown in, such as the valve voltmeter.
