Thanks morzh, I bought them new from vacuum tubes inc. and checked them on my 177a military tube tester a few months ago. They tested good for no shorts and emission. I will retest them. I thought about the higher voltage because the tube was out. The 42 calls for 300v P to K. and the 456 v. I got I guess is not too high with tube out? I took all the readings for each tube and can post them if that will help. I was double checking on the ot wiring just to be sure. Mike
