What meant "weak"? Perhaps they had lost a bit of vacuum? Or a problem with the cathode? I remember that we had a B/W TV, and the technician would come to our home now and then, and replace a tube or two. I was a kid at the time. Also, the thing was VHF only. There was only one TV channel in Spain. At some point they created a second channel, on UHF. We had our TV upgraded, a second tuner control was sticking out on the side. For this operation they took our only TV to the repair shop for some days. I think we had to install a new smaller antena for this channel to work. It had cartoons at about 20 hours, and sometimes there would be interferences and I would get mad because the only TV program I was allowed to watch was not working. -- Cheers, Carlos.
