Oran, Thanks for starting this discussion. Here are the values you were asking about. When everything is connected, what voltages do you see: At 15V TP. 1.675vdc At the emitter of Q1546. 1.683vdc At t

Got a 465 that was somewhat functional but no trace with blown F1419. Went thru Groupsio file library and replaced the C1419 and that got the signal trace. Reviewed the Power supply and here are the o

Jared, My thought is the CRT Grid Bias calibration needs to be done. Craig

Jon, Static precautions need to be followed when handling. I’ve heard about cleaning the hybrid mating surfaces with the iso alcohol, but personally never done it to solve any issue. Why would you hav

This a a repost of Chuck Harris description of a 2445b to 2465b hack job. Maybe this will help you find out if you are dealing with a true 2465B. This information was obtained by searching Tektronix 2
