Most likely, your culprit is bad paper capacitors. It could be a tube...but poor/leaky old caps are more likely to be the problem.
Why would you want to do that? The 50L6 should provide plenty of volume. You can't expect something like a 38-690, but a 50L6 can easily provide lots of audio, enough that you will only have to turn the volume up a little bit when you have it working properly.
I have a 41-226 "Sled" which has a similar 50A5 (loctal) audio output tube. This radio is actually supposed to have a 35A5, but the 50A5 allows the radio to operate comfortably on today's higher line voltage. Anyway, my 41-226 is plenty loud for me; I never have to turn the volume more than 1/2 of the way up - and most of the time, 1/4 of the way up is plenty loud.
