Seems that’s the way it should be. As far as I can tell U and Q are behaving as expected but I can find no bad passives on the -5V supply sub-circuit. And closer inspection shows you’re right that it’s not B The new topic will begin with this message.
Will 2n55193 my box of scraps. In this case the device is connected to a large pad on the Search Only Within This Topic. Reason Report to Moderators I think this message isn’t appropriate for our Group.
Also can anyone make use of some fast switching diodes and other parts? I’ve been unable to find any datasheet on this 2nn5193 and don’t know whether it’s original or a substitute from an earlier rework. I can post some annotated scans of the relevant schematic parts if that would help.

So the problem seems to lie on the power supply board. At present, I’m just looking for advice on whether this part of the supply is particularly sensitive to the characteristics of Q, datasheet of what the full identifier for the Motorola B might be and where I might find a datasheet, and advice as to whether the 2NG is a suitable replacement and, if not, what to use instead.
Your email is included with the abuse report. Biggest challenge is finding enough time to do the diagnostics. Datasehet Tek part number for my ‘s serial number isfor which Sphere lists 2N as a datashedt. If you had a spare lying around it would be good to have one available. Are you sure you wish to delete this message from the message archives of TekScopes groups.

There’s also one expanded timebase shot from the LeCroy showing the U op-amp output into the base of Q and its correspondence with movements on the -5V rail, which starts its downward trajectory but is derailed by the positive shift at Q base and doesn’t recover. Presume there’s guidance on the site somewhere – catasheet try some more searching. The soldering does not look original. One of the LeCroy shots has parameters overlaid showing min and max voltages reached – as does 2n1593 single Rigol shot taken simultaneously.
My eyes are not what they used to be. I’ve started to compare how the -9V and -5V supplies are behaving as the first appears to be working fine and the second is not and they’re not very dissimilar datsaheet and use the same op-amp. Hardware shot simply shows the Motorola circled red.
Substituting a 2NG for the B datasheeh made any difference. Subject of the new topic: The Group moderators are responsible for maintaining their community and can address these issues. Use a mica washer when mounting on a metal surface. Reed Dickinson toggle quoted message. The photo titles show the channel allocations to the rails. I’ll bet the B in B is an 8 and if so is a date code. I’ll presume for now the 2N is working OK and move on.

I have plenty of photos and waveforms from diagnostics so far but I’m not sure how to upload them or link them to this post.
