Read more carefully, Bob. It was a joke based on a typo.

Hi
I wouldn't go to crazy digging up a 10K pot. I suspect that anything in the 10K
to 50K range will work ok.

Subject: Re: [time-nuts] Isotemp OCXO trimpot question...
I don't know if the list allows attachments but I tried to attach to this
email a datasheet for a very similar Isotemp 10Mhz OCXO (Model OCXO134-10;
PN 6624.00002). Just in case the attachment doesn't come thru here is the
relevant section.
I am not certain whether the pins are the same as your model but I believe
all the Isotemp OCXO have same arrangement:
3. ELECTRICAL FREQUENCY ADJUSTMENT
3.1. Range> ±0.45 PPM
< ±1.2 PPM (At time of shipment) (Referenced
to nominal frequency)
3.2. Control 0 VDC to Vref (0 VDC to +8 VDC ) or a 10 kW
potentiometer connected between pins 2 and 4 with wiper connected to pin 3.
3.3. Slope Positive
3.4. Center Vref/2 ±10% of Vref (+4 VDC to +0.8 VDC)
