I think Mark was suggesting that. As I explained its a odd package.

Hi
Can you pull the crystal? sure.
Does your MV-89 have a 5 MHz crystal (the frequency doubled version) or a 10
MHz crystal? (sub harmonics viewed on a
spectrum analyzer are a really good way to tell).
Is the crystal the same size / pinout? Probably not. HP used an odd package.
You might be

I tend to agree with you on Bob. But that said the 10811 crystal is a bit
odd.
Its actually a copper cylinder with a screw on top. I believe to insure
correct even heat distribution. There are pix's of it on one of the sights.
Maybe the crystal comes out of the copper.
The 10811 used in the Z3
I have a wonky Morian MV-89... probably the well know output cap failure. I
wonder if one could pull the crystal out of that and stick in the HP10811?
Something tells me Bob would know ;-)

OK the 10 MHz Piezo oscillator from a lucent RC/xtal pair does work and the
3801 is doing what it should.
Some insights as mentioned. 3801 DAC being full scale is not an issue when
a good signal within 2 HZ is used it will come out of limit.
The DAC output was driving the piezo far to widely I ad
