Does anyone know what the power supply should draw when connected to an external power supply? At 40 volts my power supply is drawing a little over 1.2 amps.

The 2200 series have problems with the rectifier diodes going bad on the secondaries. Use something like 1N4937 diodes as replacements. A very fast or higher speed is necessary as replacements. The

Yeah, that is another possibility. Thanks, Mac. Jim

Yes, the opportunities for creativity are endless! Thanks for the ideas, Dave! Jim

I just saw some TM-5xx rigid extenders on ebay for $60. Item # 223811718800 . DaveD

Well, perhaps you can disguise them as picture frames for your wife's favorite pets or flowers or something when they're not in use in the lab. You could even put LEDs in to light the photos. Or use

The TM515 power supply assembly, which includes the backplane with the connectors for the modules, can be easily removed from the frame by removing the obvious screws on the rear panel. With a few

Increasing the intensity increases HV PS drain, which is causing the HV to sag. Reduced HV expands the trace. So, yup, you've got PS troubles. Look first at the usual suspects (e.g., bad bypass caps

Ah, a TM501 and a TM502, in addition to a larger one to hold multiple plug-ins.? The wife is going to LOVE that idea!? Thanks for the inspiration, Dave!? LOL!? ? ? ? ?Jim?Sent from my

Hi, I found a Tek 2236 scope in the garbage. After running it for a few minutes, the power supply failed. Powering the scope from a 42 volt supply caused the NPN transistors to fail. I replaced the

For DIY, give a try to my own very project: https://github.com/anotherlin/tek_tm_ext Here are some more photos: /g/TekScopes/album?id=243643

Zenwizard has a 2 slot unit he's using for open access.?? You'd need the TM5002, of course. Harvey

You'd probably want to use the smallest TM module in which the plug-in will fit. That way one can get to three sides of the plug-on. I have a TM-501 dedicated for troubleshooting single-bay plug-ins.

Depending upon where the fault(s) is, you will certainly need three full-size extender cables and one daughter cable: I encountered just this situation when repairing a CG5001. I have some images of

Hmmmm.... The "remove the sides" trick probably won't work on a TM515 portable like mine, though.? Darn, I guess that means I'll have to scout for a TM506 or TM5006 or a smaller TM50X mainframe.?

Dave Daniel’s suggestion regarding access to the innards of the plug-in via removal of the side covers of a power supply module works very well providing that what you are after is accessible via

You really should have asked for some advice here before hacking into that CG5011. The encoder with a broken shat is repairable - you shave off the plastic ends of the posts clean up internally and

From pages 34/ 35 of the P6022 user manual: 204-0362-02 BODY "ASSY,PROBE:LOWER" And the user manual is here: https://w140.com/tek_p6022.pdf This is the lower half of the body shell that does not

You'll almost certainly need to make an extender for the individual boards in the CG5011 as well as having extenders to connect to the TM5000 frame. See e.g.

You would probably get much better mileage and exposure from your sales offer if you do it in a separate dedicated posting. Good luck with the sale.
