Had the same problem on my Philco 90. After doing a little monitoring with my scope and generator, it was not in the amp section but in the front end. Well tubes tested good, caps were changed and resistors checked fine. I just replaced the resistors and all was well. Can't tell you the one that was the problem but seems as was suggested sometimes the old ones work well until a little heat. Just a suggestion.
