Guessing this guy was built > 30-40 years ago. If it was mine I would replace all the smaller ones. Get it over and done with. The ones that have screws, you can take the chance of putting a scope across them (watch out if they are floating !!) and look at the ripple, I any over say 2%, they are more than likely bad, but you can see if the reform or not. More then a couple % and you can damage things. Other things I do Check the voltages quickly Check the thermal grease on all the heat sinks. -pete PS keep your eyes open from replacement lamps.
