OK. I was wondering. There are no details in the parts list.

Yes, but most glues don't adhere well to aluminum due to the oxide on its surface. OK. Well, 
I can figure something out.

Well, in this case, not really. The one I am working on now was bought by a local friend at a 
garage sale for about $50 complete with HP-23 and a speaker. It had been built very well, 
but had obviously not seen much use, if any. The problem was that after the rig warmed up, 
the VFO would quit. I'm sure the original builder never figured it out. The FET in the VFO 
was bad, as I may have mentioned here. Your suggestion of a 2N5486 (if I have the number 
correct) was what I used, and the VFO works very well now.

I was about to button it back up and reinstall it when I ran across that info in the manual and 
thought I should implement that.

Very neat, Chris! :-)
