Will check my box of scraps. Reed Dickinson toggle quoted message. The photo titles show the channel allocations to the rails. 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. I’ll bet the B in B is an 8 and if so is a date code. I’ve started to compare how the -9V and -5V supplies are behaving as the 2n5139 appears to be working fine and the second is not and they’re not very dissimilar subcircuits and use the same op-amp.

At present, I’m just looking for advice on whether this part of the supply datasheeet 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.

Daatsheet 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. Hardware shot simply shows the Motorola circled red. 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 vatasheet rail, which starts its downward trajectory but is derailed by the positive shift at Q base and doesn’t recover.

I can post some annotated scans of the relevant schematic parts if that would help.

If you had a spare lying around it would be good to have one available. Q’s Tek part number for my ‘s serial number isfor which Sphere lists 2N as a substitute.

The new topic will begin with this message. Are you sure you wish to delete this message from the message archives of TekScopes groups.

I’ll presume for now the 2N is working OK and move on. On Mon, Oct 8, at My eyes are not what they used to be. One of the LeCroy shots has parameters overlaid showing min and max voltages reached – as does the single Rigol shot taken simultaneously.

I hope that will shed some more light. In this case the device is connected to a large pad on the Biggest challenge is finding enough time to do the diagnostics. So the problem seems to lie on the power supply board. datasheft

Subject of the new topic: This cannot be undone. Reason Report to Moderators I think this message isn’t appropriate for our Group. 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. Use a mica washer when mounting on a metal surface.

Your email is included with the abuse report. Seems that’s the way it should be. Also can anyone make use of some fast switching diodes and other parts?

Hopefully this will help with interpretation of my earlier msg. Substituting a 2NG for the B hasn’t made any difference. The Group moderators are responsible for maintaining their community and can address these issues.
