P6139a with broken tip

Lawrance A. Schneider
 

Hello everyone,

I recently sold my ‘extra’ 2445B to a friend. It was a very good system - had had the fan replaced and was exceptionally clean; the caps all checked out etc… Why did I sell it? Money. I had been lucky and acquired a 2465BDM making the 2445B extra. The 2465BDM cost me money - strange how that works. While the new 2465BDM works well, I’ve not had a chance to change the fan nor check the power supply caps. I’ve only had it for two weeks.

Now the problem. The new system came with broken probes. My friend wanted probes with the 2445B. Had I sold it on eBay, I would not have included the probes. This sale was to a friend!

The P6139a probe was designed for that series of scopes. Tektronix does not make the probe any longer. Tek no longer sells components for that probe. The tip (206-0441-00 PROBE TIP ASSY 10X, 8.0 PF, 9 MEG) is what is broken; the actual pin is missing.

Should I try to replace the pin - has anyone ever done so?

I see on eBay Chinese probe tip knock offs for $40 - $50. Are they good? I also see that Probe Master sells: 5900 Oscilloscope Probe Kit, 500 MHz, 10X. They want $189!!!!

I have 2 functioning probes. Any suggestions?

I will try, old farts disease, to check our spare parts box. We have about a cubic yard of scope probe parts, but I think I’ve looked for the 6139 stuff before. I’ll let you know and then drop them in an envelope for you if I have them.

Don’t need a few 465 style 1x/10x probes do you, we have about 150 of them.

Hi Mr. Hanselman (may I call you Steve or Stephen?),

Are you related to Professor Hanselman at UMO?

I see you are a disabled vet! I’m a 100% disabled vet and it is great to see you have your own business! CONGRATS!!!

I’ve been told the the 465 probes work fine ; they just have a little higher db loss. What would I owe you? You say you have a lot, I could get some for my friend as well?

Thanks, larry

The 2465B originally shipped with P6137 probes. They too are difficult to find in good condition, and at a good price.
Many cheap probes will work, how important is signal fidelity to the user?
Tek probes were very carefully designed for the vertical system of the specific instrument.

The P6139A was designed for the 500 MHz TDS-series (TDS500 e.a.). The P6137 was designed for the 2465B.

Well, that is what I have and will continue to use ’till I win the lottery; since I don’t play…'

Anyone looking for a replacement tip for a P6139A:

Cal Test Electronics CT3667 is a perfect alternate.

$22.50 on Mouser.



I just got two, compared performance (rise time and ability to compensate)
and it is a perfect match. I used my PG506 to measure rise-time, and when I
superimposed an original 6139A with the replacement version they are dead on
top of each other. (using a 1GHz scope).

This is great new for use P6139A fans!

Do they have similar tips for P6137?  Or is this one sufficiently
overqualified to work well enough?

Hi,

I just posted a new query elsewhere on this board with similar thoughts: can I use a CT3667 (206-0441-00 equivalent) used in P6139A to replace a 206-0378-00 used in a P6137?

Dear Mr Hanselman,

Thank you for expending the effort to publish the list above with oscilloscope probe replacement tips. Unfortunately, I don't see any of the type that I need (206-0378-00). Hopefully some others can benefit from your inventory list.

Regards,

Jan Kolek

Jan,
As you may have noted there are several w/o part numbers. What are the colors probe tip and the other end?

Steve,

I looked those over as well and didn't see a match. The 206-0378-00 is a 3.5 mm probe tip assembly with black on the probe tip end and clear/natural on the tail (threaded) end.

Steve,

The probe tip assembly you have labeled as "Blue--Yellow - 206-0440-00 - 7ea" might actually be 206-0441-00. P/N 206-0440-00 is the part number of the connector/compensation box for the Tektronix P6139A oscilloscope probe.

Sorry we didn’t have what you needed and thank you for the correction
