First I suggest you let it run for a couple of weeks to see if it will come
into range. It can take time for moisture to be driven out and stresses to
be relieved.
If you have to go into it, it comes apart very easily. Just be very careful
not to break the flask. You probably couldn't get a replacement.

Hi
The 1115B got here yesterday. It seems to work pretty well. Not to
surprisingly it's drifted a bit over the last 35 years. It's right at one
end of it's 2.7x10^-7 tune range.
From what I can see in the manual there's an adjustment on the crystal
board that might bring it back onto frequency. Since getting there
involves disassembling the dewar flask / oven combination I'm a little
hesitant to dive right in. Has anybody torn into one of these before? If
so what am I likely to run into? Everything I can see is wide open and
very easy to work on. I'm hoping the oven is built the same way.
Thanks!
Bob
