Yes indeed I know these well they are used in the Odetics GPStar rcvr.
They can be disciplined quite well. Also fast warmup and the power goes
down pretty quickly.

I've used a variant of this one, I haven't checked all the details.
Never the less, it does a good job and many competing products eat the
dust for the size and price.

They are heavier than any competing product in this size I have seen,
but then you have to recall that the AT-cut crystal rod is burried
inside a FR-4 casket giving thermal mass, and this is somewhat floating
from the surrounding metal case. The result being better ability to
handle thermal stress in the form of sudden temperature shifts.

Cheers,
Magnus

Dear Magnus,

Thank you. I didn't notice until your last message. Nice opportunity. I immediately grabbed a couple of them. You never know when you will need them.

How kind of you to share this information.

You have a nice weekend!

I made an offer of 14 pounds each for two of them that was accepted.

I wonder what the temperature it runs at is? maybe put it inside another
oven that uses a PTC heater.
