COSSOR

I'm keen to get some more Cossor manuals on-line.
If you can help with any such equipment ? If so please
contact me via the Guestbook page.

Cossor 343	Cossor 343 frequency modulated ganging oscillator. The manual includes a useful section on radio alignment procedure, also includes schematic.
	Instruction Manual 343.pdf [1.8M]
Cossor 339a	A huge 90-odd page manual. If you just want the basic info for servicing the instrument you just need part 5. Part 3 contains general information on using oscilloscopes.
	Part 1 : 339_1.pdf[629K] General description (including components). Part 2 : 339_2.pdf[410K] Operating instructions . Part 3 : 339_3.pdf[389K] Operating conditions.

Cossor 1049	Specification, circuit description, parts list and circuit diagram. And not an electrolytic in sight ! This 'scope uses some odd Cossor valves and the manual omits any pin-out information. I therefor knocked up the second document which includes pin-out information plus list of valve alternatives.
