At the front of the bottom of the cabinet there's a 4x6(?) inch black ribbed rubber pad. If it were metal I'd say a heat sink.

Wht is its purpose?

Thanks,
Dave

Not many have this. The only use I can think of was to protect the case when putting the scope on the recommended scope cart which tended to scratch that area of the case.

That black rubber/plastic thingee, as I recall had room in it to fit over the seam of the cabinet was required addition to the 2465 cases. I can't remember exactly, but it kept the case from getting pushed into circuitry. Maybe something to do with the counter timer, I just can't exactly recall. It was added to the front bottom of the case, with minimal clearance of the front panel

The rubber pad you talk about is not present on my Tek 2465. My serial no. is
B0536XX. Could it be some ones modification?

Looks factory standard (or optional):

Some other responders have said that some scopes have it, some don't. The best explanation I've heard is that if you put the 2465 on a scope cart the folded metal seam in the cabinet is pressed into the A1 board. By installing this piece it distributes the load of the scope on that point so that the seam is not depressed (the pad is notched to fit over the metal seam.)

Hi all,

As an addition to my collection I recently got a 2465 that had the rubber/plastic ribbed pad as well.
The cut-out in the material to me makes it a TekTronix original, especially because it keeps the ventilation holes exactly free.

It either serves as extra protection for the bottom, and by doing that extra protection for the interior electronics,
it also can be a saveguard that prevents the ventilation holes to be blocked when stacking devices, as people often do.

Un saludo,

The pad wasn't available until after the 2465 had run its
course, having been introduced with the B models... after
serial number B050740, I believe. It was available as a
modification kit for all models.... and all cabinets are
interchangeable, so some mixing and merging has certainly
occurred over the years.

Its purpose was two fold. It is pretty popular to put the
2465 on the shelves that are above most commercially made
workbenches. And those shelves are usually too short to
allow the 2465 to sit upon its feet, assuring proper ventilation..
The 2465's fan sucks fresh air through the holes in the cabinet
in places where it is needed, so undoubtedly some scopes were
damaged by having the holes around the vertical preamp hybrids
blocked by the carpeting that is commonly on these instrument
shelves. The black plastic keeps the scope up enough to allow
air to flow where it must.

The secondary purpose is to prevent damage to the cabinet that
would make it hard or impossible to remove. The vertical preamp
covers have hard points where the springy grounding clips are
mounted to the back of the preamps. If you bend the cabinet
in this area... even a little..., you won't be able to slide it
by those hard points, without cutting the cabinet.

It is a good thing to have.

I saw the explanation for the rubber pad, I think on the VintageTek site, from an engineer on the 2465 project. The reason the pad was included was, there were incidents of the input attenuator ceramic substrate being broken if the instrument was impacted on the case bottom rather than the feet. Something about the case seam transferring the force into the substrate. As I recall the case seam was also moved off center.
I have replaced a few broken attenuators, but didn't understand the mechanism.
If I can find the info I will ad it.
