| That's a good point Rich. In any case, a minor adjustment to the primary 
will bring the filament right to where you want it. I'm a firm believer in 
step start for filaments on expensive tubes as well as high voltage 
supplies.  Thanks!

necessary to be able to adjust the filament V more than +/- 8%.  A 
rheostat does the job nicely.

 An easy solution would be to obtain one of the small variable 
transformers (I have a couple I bought on Ebay) and put it in the 
filament transformer primary so you can make the necessary minor 
adjustment.  73, Tony W4ZT
