[Boatanchors] IERC shields

[hwhall at compuserve.com]

      From what I've looked up for my own purposes, the 6BA7 is a T 6 1/2 bulb and the 6BA6 is a T 5 1/2 bulb. The IERC shields to fit ought to be TR6-6020 and TR5-5015, respectively. Varieties in construction or finish detail apparently can alter the TR part of the nomenclature or add a letter suffix. A quick look at the Surplus Sales site didn't reveal the 6020 size but they had the 5015 for $2.50.

If anyone can provide info on the meaning of the suffixes, I'd like to hear it. Haven't been able to learn that on my own.

  Hi Doug, 
 Surplus sales of Nebraska has any size with competitive prices.  They also  
 have the socket adapters for the shields. 
  
 Kindest regards Jim K9AXN

 Looking for two IERC tube shields w/serrated contact liner for the 6BA6  
 (about 3/4" did, 1 3/4" tall approx) 
 and one for the 6BA7 (about 1" did, 2 1/2" tall approx). 
 QSL W5JV with price & availability.  Still looking for a crystal which is  
 close enough below 1770 to beground up to 1770 KHZ.  HC6 OR FT243 OR ??? 
 Thanks, 
 Doug W5JV
