I have been working on my 1964 KWM2A for the last few days. Just your basic clean up and tweeking you have to do when its been sitting on the shelf for too long. Everything seems to be working very nicely right now. I only have one concern. V13  6U8A has a slight blue glow to it like its gassy. I have change the tube out a few times and its still there. So my next guess would be that something in that circuit needs to be look at. The first thing i did was get the resistance chart for the tube sockets. the only thing that i could find out of res was pin 6 which should measure 8K. It mearsures 10.51 K  Could that be my gassy effect or should i dig deeper or just don`t worry about it? The only thing i could find wrong that could be a little problem in that area would be that my audio on the 4 Ohms speaker is not the nice perfect audio that you should get from a KWM2A and my calibrator is a wee bit off, I will look on my schematic again.  What do you think Boys am i just being a worry wart?
