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
