Hey JBG, good to see you are still around! I did check connections and microphonic tubes, but no go. The thing is it seems to be getting worse, more frequent yet unpredictable and happens at any odd moment. From that I am thinking it might be time to get it checked out. I just cooresponded with Craig at www.nosvalves.com. I think he has the right philosophy (no wild modifications, just get it back to spec since Scott engineers knew what they were doing), So, I am about 99% sure I am going to have him work it up. What do you think? Am I making a big potential mistake? I have read all the warnings here, but I still can't see how something this old couldn't benefit from being worked on.
Thanks
Thanks
