Hi Joe:

Looked into this a little bit, and no one seems to have the answer.
My Corsair PTO drifts about 200 Hz in 40 min, then back 100 Hz and then
stable for a while unless I open the window.  A good breeze will
take me 50 Hz in a half hour it seems.  

I suspect we could just stick a small light bulb inside the PTO
case and leave it on, if we could figure it would bring it all up
a few degrees and keep it there.  That might do it, I think I saw
someone on this list with that idea.

We could also just play with the caps that are compensating in 
there to get them right.  I don't have experience in that, and 
experience is what makes that sort of experimentation work as I
understand it.

Anyone have ideas on stabilizing the older Ten Tec PTO's?  Don't 
need perfection, if we could just keep it down to a small amount
it would help a lot.
