I'd extend that advice to all of the tubes. The first thing I do in every project (well, first after brushing away the dust) is to clean & test all tubes, as well as all controls & switches.
I remember the CTC-11's service switch well, and that's one reason why I've become eager to clean everything early. After recapping, the set worked very well except for one weird symptom. It was magically cured when Bill asked whether I had cleaned the service switch!
