I have just acquired one of these 'scopes in a partly working state. Does anyone have schematics for it? Channel 1 is blank unless the "pull to invert" switch is set halfway. I thought the switch was faulty but it tests ok, so looks like some problem in the ch1 amp. Think I might have blown something by mis-wiring after taking it apart to replace the same switch on channel 2 - which now works btw - previously it didn't but ch 1 did. Duh.
