I forgot to mention that the album is named "Tek 2465BCT CAL01 weird behavior."

Yes Roy, I think "breadboard" or "solderless breadboard" are the names commonly applied to those things. When I was writing the message, my brain was in deep memory fetch mode, and the name escaped

Rogerio O added the album Tek 2465BCT CAL01 weird behavior.: This are photos and movies of what I get when trying to execute CAL01 routine.

In my little post I mentioned working in a resistor factory during part of mis-spent youth. We made film resistors exclusively so I don't know a lot about making composition resistors. However, I

Dear All, After fixing the A5 board of the scope which was damaged due to capacitor leakage I have started to try to calibrate the scope. I managed to adjust DAC REF without any issues and moved to

On a few occasions I've had to trim carbon comp resistors by carefully filing partially through the body with a fine file or a fine saw. In one case I know that the packaging machine that I installed

Hi all. I'm currently restoring my DM502 Digital Multimeter and am looking for a few parts. Specifically, I need the 'dB' and 'INT' push button caps (with writing in good condition) and hopefully

Aren't there two types? The coarse ones for the 500 series and a finer pitch one?

by that phrase, you mean a "breadboard?"... which is certainly not a board, nor has anything much to do with bread; but, is as descriptive as calling a peanut a nut. There might be a reason that

Monty: My 4041 has a full complement of functionality. It has the full 512KB ram memory. The system looks basically like it is brand new. I would be interested in purchasing one of your 5-1/4"

In my earlier days (pre 1970), I used to "trim" carbon composition resistors by carefully overheating them with a soldering iron to raise their values slightly. This may have also improved their

I have repaired a 465 (not "B") in this manner. Actually "reassembled" that little plastic part on the shaft from the pieces recovered from inside the drum. Tedious job, but JB Weld did the job.

No, in hindsight (after reading your messages once more) I see that your 'scope very likely has another problem. After some searching in the manual I found U1720 at diagram 25, board A29. It would

I'm going to post the picture(s) I took of the disassembled Time/Div switch assembly. D.

I think JB Weld is a good solution for the B switch cam/shaft joint. It's slow curing, and yeah, the knurling will make a great bonding surface. And I can see where I need to be super careful about

Just a suggestion for gluing plastic to metal. I have found the slow-cure epoxies to be generally stronger than the quick-cure ones. I bought some "industrial" epoxy from Loctite (Hysol 1C - not

I was showing my wife what happened and went through the 465B and 475 parts manuals from the Tek Wiki. To show her how similar the scope faces are, but also to look up the part numbers in the service

How similar is the 465's sec/div switch cam to the 475's, I wonder. I've got 3 "parts" 475s and could probably spare one of the switch cam assemblies. If you had a full drum and shaft assembly would
