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, 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. 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.

This cannot be undone.

Substituting a 2NG for the B hasn’t made any difference. I’ll bet the B in B is an 8 and if so is a date code.

The soldering does not look original. Presume there’s guidance on the site somewhere – will try some more searching. My eyes are not what they used to be. I’ve started to compare how the -9V and -5V supplies are behaving dqtasheet the first appears to be working fine and the second is 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. Your email is included with the abuse report. 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 Subject datasheef the new topic: In this case the device is connected to a large pad on the Search Only Within This Topic. Also can anyone make use of some fast switching diodes and other parts?

Seems that’s the way it should be.

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

Use a mica washer when mounting on a metal surface. The new topic will begin with this message. 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 can post some annotated scans of the relevant schematic parts if that would help. Will check my box of scraps. The photo titles show the channel allocations to the rails. 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.

dataseet 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. On Mon, Oct 8, at The Group moderators are responsible for maintaining their community and can address these issues.

Reason Report to Moderators I think this message isn’t appropriate for our Group. Hardware shot simply shows the Motorola circled red. Biggest challenge is finding enough time to do the diagnostics. Reed Dickinson toggle quoted message. I hope that will shed some more light.
