Having now borrowed my friend's Variac, what is seen as
good practice for ramping up old valve radios to reform the
capacitors?

Start off at, say, 50VAC and then increase by 50VAC every
1/2 hour until 240V is reached?

Try connecting the Variac output to various bits of your anatomy. (Assuming
you have croc clips small enough for some of them, of course)
