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 datashete and the second is not and they’re not very dissimilar subcircuits and use the same op-amp. The photo titles show the channel allocations to the rails. Also can anyone make use of some fast switching diodes and other parts?
This cannot be undone. 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.
The Group moderators are responsible for maintaining their community and can address these issues. I’ll bet the B in B is an 8 and if so is a date code. I’ll dahasheet for now the 2N is working OK and move on. Seems that’s the way it should be. On Mon, Oct 8, at Biggest challenge is finding enough time to do the diagnostics. Search Only Within This Topic. 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 adtasheet, which starts its downward trajectory but is derailed by the positive shift at Q base and doesn’t recover.
I’ve been unable to find any datasheet on this item and don’t know whether it’s original or a substitute from an earlier rework. Reed Dickinson toggle quoted message. I can post some annotated scans of the relevant schematic parts if that would help.
Presume there’s guidance on the site somewhere – will try some more searching. Use a mica washer when mounting on a metal surface.

Subject of the new topic: One of the LeCroy shots has parameters overlaid showing min and max voltages reached – as does the single Rigol shot taken simultaneously. Will check my box of scraps. The new topic will begin with this message. The soldering does not look dattasheet. Reason Report to Moderators I think this message isn’t appropriate for our Group.
So the problem seems to lie on the power supply board. I hope that will shed some more light. At present, I’m just looking for advice on whether this part of the supply is particularly sensitive to the characteristics of Q, details 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.

2N PNP Transistor
Are you sure you wish to delete this message from the message archives of TekScopes groups. And closer inspection shows you’re right that it’s not B If you had a spare lying around it would be good to have one available. Substituting a 2NG for the Datasheey hasn’t made any difference. In this case the device is connected to a large pad on the 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.
Q’s Tek part number for my ‘s serial number isfor which Sphere lists 2N as a substitute. Hopefully this will help with interpretation of my earlier msg. Hardware shot simply shows the Motorola circled red.
