Adrian,
if you do not insist on a hp10811A, have a look at Gerrys site

You can buy an assembled option 10 compatible OCXO modul for less than
100 GBP.
I built DIY one with a PCB from Gerry
Hi
If you *need* portability, an internal oscillator is a good thing. If you want
to fire something up fast, an OCXO is not a good choice. That’s a bit of a
problem.
A few real choices:
1) Get something like the LTE that locks up to GPS and runs right away. When
portable, bring along a
I've seen Gerry's board and might well fit one to another counter.
However, this already has a suitable board - in fact, it appears it is
an oven, not a tcxo. Presumably just not as good an oven.
The point is, it looks ready to receive a 10811A. In fact, consulting
the assembly-level service

Is the upgrade similarly easy on a 53131A ?
I realise that it needs to have an additional controller pcb but I
have one of these counters fitted with option 001. The pcb holding the
oscillator has an edge connector that looks suitable for a 10811A, and
I have one to hand as well as a couple of

Just remove the TCXO the 10811 just plugs in, you will need to add the heater
oven indicator wiring and LED indicator which is usually over the power switch
The power supply includes the oven supply already

Note that there are many different versions of the 10811. I am familiar
with at least two incompatible mechanical configurations: one is
connectorized and the other is not.

Hi
In this case I suspect he’s referring to the version with the edge connector on
it. That’s the one most instruments use rather than the connector only version
or the “double oven” version. I believe that makes it a 10811A rather than a
10811B.
There are a multitude of details here:
You are correct I was referring to the 'instrument' version of the 10811A with
the edge connector.
There are a lot of 10811A variants out there but the edge connector version was
used in most HP instruments with an ovenized time base of that vintage.
It's worth buying dead option 1
