Default Re: Tektronix 475A intermittent sweep

No have gone through that and tested it. Seems to be trigger related. If I inject something into ext trigger it doesn’t reliably trigger, deciding to do so randomly and intermittently.

I’m watching the input of the monolithic input preamp and the gate input.
