Bringing up old valve radios slowly?

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? If the caps are dry it's unlikely you'll reach that. -- J |
