Actually, 'IT' was quite dirty to start with. I try to stay clean.

I was quite dirty to start with though.

About two years ago I had to power it down and store it away in climate-controlled storage during a remodeling project. Last night I got it back out of storage and powered it up. Initially, after the ovens had warmed up I was able to get it to lock, but by this morning it had unlocked. I noticed that the 2nd harmonic, which last night had been reading close to its historical value of 30 on the meter, now read 0. Opening the loop for a few seconds and then closing it made the 2nd harmonic reading go back up to 30 for two or three seconds and I was able to get the continuous operating light to come on, but then the 2nd harmonic drifted back down to 0 and the green light went out. I have the O&S manual, but it's still in storage. Since, it's been a while since I played with this instrument, I'm wondering if someone can tell me what's going on, where I should start looking, and what, if anything, I can do to correct the problem.
