Thanks Paul and Scott for weighing in with your thoughts. I "sucked it up"
and blasted all the sections of all the tube tester rotary wafer switches
with Deoxit D5 last night. The tube checker works great now. I had been
having some anomalies on a box of new 6146s I got and couldn't believe all
of them were equally erratic. I also had been having a problem with the
needle hanging up. I tried the old Navy kitchen detergent trick and it still
hung up. While I was blasting away with Deoxit I removed and dismantled the
meter...did a treatment of kitchen detergent INSIDE the meter face....and
the problem went away. Not only to I have a nicely flowing and well damped
meter movement now but I also have a very, very clean meter case to look
through!

Paul...I am going to look for some of that CRC tomorrow. Deoxit is good but
I am always interested in trying something else.

My best,
