Silicon PNP Power Transistors

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, fatasheet advice as to whether the 2NG is a suitable replacement and, if not, what to use instead. Your email is included with the abuse report. I’ll presume for now the 2N is working OK 25193 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 dataaheet recover.

The photo titles show the channel allocations to datashewt rails. Hopefully this will help with interpretation of datahseet earlier msg. Are you sure you wish to delete this message from the message archives of TekScopes groups. The Group moderators are responsible for maintaining their community and can address these issues. I’ve started to compare how the -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.

Biggest challenge is finding enough time to do the diagnostics.

Substituting a 2NG for the B hasn’t made any difference. 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. This cannot be undone. 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. Subject of the new topic: Search Only Within This Topic.

Reason Report to Moderators I think this message isn’t appropriate for our Group. Will check my box of scraps. And closer inspection shows you’re right that it’s not B My eyes are not what they used to be. In this case the device is connected to a large pad on the So the problem seems to lie on the power supply board.

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. 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. I hope that will shed some more light. The soldering does not look original.

I’ll bet the B in B is an 8 and if so is a date code. Hardware shot simply shows the Motorola circled red. On Mon, Oct 8, at I can post some annotated scans of the relevant schematic parts if that would help. Use a mica washer when mounting on a metal surface. Also can anyone make use of some fast switching diodes and other parts? If you had a spare lying around it would be good to have one available.

One of the LeCroy shots has parameters overlaid showing min and max voltages reached – as does the single Rigol shot taken simultaneously.
