2N Central Semiconducto

The new topic will begin with this message. Seems that’s the way it should be. Biggest challenge is finding enough time to do the diagnostics.

I hope that will shed some more light. And closer inspection shows you’re right that it’s not B This cannot be undone.

2N5193 Datasheet

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.

The soldering does not look original. Hopefully this will help with interpretation of my earlier msg. One of the LeCroy shots has parameters overlaid showing datahseet and max voltages reached – as does the single Rigol shot taken simultaneously. Subject of the new topic: I can post some annotated scans of the relevant schematic parts if that would help.

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

Hardware shot simply shows the Motorola circled red. If you had a spare lying around it would be good to have dataeheet available. 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. On Mon, Oct 8, at 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. Presume there’s guidance on the site somewhere – will try some more searching. I’ve started to compare how datasueet -9V and -5V supplies are behaving as 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.

Your email is included with the abuse report. 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. In this case the device is connected to a large pad on the So the problem seems to lie on the power supply board.

The photo titles show the channel allocations to the datasyeet. 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.

My eyes are not what they used to be. Use a mica washer when mounting on a metal surface. Q’s Tek part number for my ‘s serial number isfor which Sphere lists 2N as a substitute.
