I've used radios and amps with tube well over 50 years old. It's the capacitors you have to watch for as they age. "Change them all at once" is odd advice. I wonder if they meant that to apply to serial-wired tubes, where the heaters were all matched to the same amperage. “Radiola” – now *that’s* a brand name!

What is a Radiotron MO1A? I saw it on a little Chinese vacuum tube amplifier, current (2007/08) model. Sorry, forgot to check the “Noitify me by email” box.
