Scott,
You may not need that many shields.
Recommendations were to shield the RF, 1st, 2nd, 3rd mixers, VFO, BFO.
Just the RF mixers and Osc need shields. Recommendations were to uncover
every thing else.
We know the good shields will run cooler than the plain cans.
I do not know if the good shields will actually get you a cooler glass bulb
temperature than no shield with ventilation being the same.
So it still may be best to run most of the tubes naked.
Just because we used those crummy old shields is not reason to continue.
We put in better caps today, so why not better shields.
Round up as many as you can. One never has enough spare parts.
