Steve thank you very much. I appreciate this advice and will try these things. I'll let you know how I make out. I checked my work, but i'll check again because I easily could have missed something. For this radio I did a lot of work before checking it out, whereas on previous sets I've done an initial power up after replacing the filter caps to make sure I had life. I guess I got over confident. Also, I do understand it certainly could be a tube, and I know I need to get a tube tester, but I've been putting that purchase off. I'm new to this, but in the dozen sets I've worked on so far only one has actually needed any new tube. I also don't know which tester to buy.
