Need Tektronix 2230 Part - But Where????

[Newman]

We have an old, and excellent, Tektronix 2230 Scope that R&D uses all
the time. They rely on it.

When it went in for annual cal, the cal lab reports that Channel 2 is
"intermittent", and they have traced it to the fact that the input
connector for Ch2 is broken.

I would have thought that this kind of thing should have been a
standard panel mount BNC connector, but apparently not.

Anyone have any idea where this part could be obtained???

We really do not want to have to buy a new scope, nor to restrict this
wonderful scope to being a "one channel" instrument!

Any & all help would be appreciated.

If all else fails you can join parts-link.com and post it as a Wanted part.
If you have a photo of the old part, that helps big time. Good luck.

The 2230 BNC input has a probe sense ring, if you don't mind losing the
auto scale factoring or if you are using uncoded probes anyway, then a
standard BNC panel mount socket can be used.

the TEK 2230 service manual should have the manufacturer for the BNC.
There'll be a 5 digit code for the manufacturer,and the list of
manufacturers is at the front of the parts list.
the same BNC is used in 400 series scopes,2200 series,2400 series scopes,7K
plug-ins.

IIRC,the TEK p/n is 131-0679-02.

Sphere in Canada may have new stock.

I had already talked with Sphere, and they don't have any.

Thanks for that part number though!

I was able to trace this to a Kings pert number: KC-79-186

Spec Sheet here (Note: the Kings data sheet actually references the
Tek part number!

You really do have to watch prices!

I found one supplier that wanted $265 US$, and one that wants $9.20!

You can probably guess who I will be buying from

Looks like the Scope is alive for a few years yet!
