Philips Oscilloscope.

I've found the service manual for the Philips oscilloscope. Lots of miniature reed switches to perform the various functions. Time to swot up before attempting any service work on it.

I realize it's a complex beast, Geordie. The manual is available on line, and, as you say, I'll have to swot up on it before going further.
