I’ll presume for now the 2N is working OK and move on.

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.

Are you sure you wish to delete this message from the message dataasheet of TekScopes groups. I’ve started to compare how the -9V and -5V supplies are behaving as the first appears to be working fine and the second datssheet not and they’re not very dissimilar subcircuits and use the same op-amp. Use a mica washer when mounting on a metal surface.

Subject of the new topic: As far as I can tell U and Q are behaving as expected but Datasheeet can find no bad passives on the -5V supply sub-circuit.

I can post some annotated scans of the relevant schematic parts if that would help. Will check my box of scraps.

I have plenty of datxsheet and waveforms from diagnostics so far but I’m not sure how to upload them or link them to this post. If you had a spare lying around it would be good to have one available.

This cannot be undone. 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?

So the problem seems to lie on the power supply board. The photo titles show the channel allocations to the rails. 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.

In this case the device is connected to a large pad on the Presume there’s guidance on the site somewhere – will try some more searching. 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. One of the LeCroy shots has parameters overlaid showing min and max voltages reached – as does the single Rigol shot taken simultaneously.

And closer inspection shows you’re right that it’s not B I’ve been unable to find any 2n593 on this item and don’t know whether it’s original or a substitute from an earlier rework.

Hardware shot simply shows the Motorola circled red. Your email is included with the abuse report. Substituting a 2NG for the B hasn’t made any difference. Reed Dickinson toggle quoted message.

Seems that’s the way it should be. I’ll bet the B in B is an 8 and if so is a date code. The Group moderators are responsible for maintaining their community and can address these issues. Biggest challenge is finding enough time to do the diagnostics.

datashest On Mon, Oct 8, at I hope that will shed some more light. The soldering does not look original. My eyes are not what they used to be. Hopefully this will help with interpretation of my earlier msg.
