Century 21 bulb miss read
 

That incandescent bulb is an 1982 NOT an 1872. Guess I need to get my
eyeball nuts tightened.

Man, I'm trying to type this darned posting in too much of a hurry...

OK...breath...

the bulb is an 1892, NOT a "1982" NOR an "1872".

Sheesh.

Anyway...TAKE THE DARNED BULB OUT OF THE METER and see if your drift
diminishes.

I believe I'll continue to drift the same amount as before. ;-)

Update
 

After 8 hours of "cooking without the meter bulb" the receiver has drifted
less than 100 cycles (50-80 cycles nominally) , far better stability than
before. To preclude any heating from the finals during long transmit periods
I am going to experiment with moving the finals to the outside of the year
of the case. I'll post my results here for anyone who is interested.
