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.
