Re: New to group - Just acquired a R7844

Hi Everybody! I recently bought a tek 1401A from Ebay (sans the tiny scope that goes with it. Alas.). It lacks the battery/charger module but otherwise seems to be complete except for a missing fine

correcting 5v supply on a 5110

Have you seen arcing around vertical output transistors?
