I have recently purchased this oscillator from ebay just as a project. It does work to a point, but not much use as it is. Unfortunately i have not been able to locate a manual or circuit diagram. So if anyone could possibly point me in the right direction it would be really helpful.
In the Wireless World magazine of April 1968 it was advertised at £150
Frequency 0.2Hz to 1.22MHz
Manual and circuit diagram wanted.
