Re: Tektronix 2465B CRT VERT pin bent?
Usually, the pins should be neither bent asymmetrically, nor straight (like they are in your other picture). The vertical deflection plate wires coming out of the CRT neck are very thin, soft, and

Re: Tektronix 2465B CRT VERT pin bent?
While I'm not an expert on the 2465B AT ALL, I wouldn't worry about the bends and I wouldn't "fix" them.? While they probably could take an adjustment to realign them, they might have already been

Re: TDS 644A Power Supply problem
I wrote up a bunch of stuff about my TDS544A repair in the group, through several messages. This was maybe four or five years ago, before the move from yahoo, I think. I haven't had much luck

Hi John, If it has a Tek logo on it this is not off topic at all. We collect, support, fix, and recommend anything made by Tek. Dennis Tillman W7PF

Re: TDS 644A Power Supply problem
OK that was a mix up. I accidentally posted to the Tek576 curve tracer thread. I am repeating it here in the correct thread so it can be found. Hi Ed; I sent you my repair log and in it you will find

Re: Tek 576 chatters
OK that was a mix up. Two threads crossed and this was meant for the TDS644A thread. And of course the capacitor was 47 uF not 47 ohms although the ESR is 7 ohms on the one removed.

Re: Tek 576 chatters
Hi Ed; I sent you my repair log and in it you will find that the reason the first transistor blew a year ago was high ESR in C17. I had replaced the Q9 and both TVR (VR4 & VR5) and Q9 immediately blew

I have looked at other Tektronix groups but they are extremely small (one had 71 members). While I agree those 71 might be experts it is unlikely. So here goes an off topic question for those with
