Substituting a 2NG for the B hasn’t made any difference.

So the problem seems to lie on the power supply board. Reed Dickinson toggle quoted message. Hardware shot simply shows the Motorola circled red.

The new topic will begin with this datasyeet. In this case the device is connected to a large pad on the I hope that will shed some more light. Reason Report to Moderators I think this message isn’t appropriate for our Group. Biggest challenge is finding enough time to do the diagnostics. I can post some annotated scans of the relevant schematic parts if that would help.

I’ve started to compare how the -9V and -5V supplies are behaving as the first appears to be working fine and the second dwtasheet not and they’re not very dissimilar subcircuits and use the same op-amp. I’ll presume for now the 2N is working OK and move on.

My eyes are not what they used to be. 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.

Q’s Dwtasheet part number for my ‘s serial number isfor which Sphere lists 2N as a substitute. I’ve been datasjeet to find any datasheet on this item and don’t know whether it’s original or a substitute from an earlier rework. Are you sure you wish to delete this message from the message archives of TekScopes groups. Will check my box of scraps. 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.

One of the LeCroy shots has parameters overlaid showing min and max voltages reached – as does the single Rigol shot taken simultaneously. The photo titles show the channel allocations to the rails.

The soldering does not look original. If you had a spare lying around it would be good to have one available. Also can anyone make use of some fast switching diodes and other parts?

Seems that’s the way it should be. 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.

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. Presume there’s guidance on the site somewhere – will try some more searching. And closer inspection shows you’re right datasueet it’s not B Search Only Within This Topic.

Hopefully this will help with interpretation of my earlier msg. I’ll bet the B in B is an 8 and if so is a date code. On Mon, Oct 8, at
