They are doing well, and it would seem that there is at least a prima facie case for these firms voluntarily reducing the price of cathode ray tubes.
I think it is true to say that if the cathode ray tube in the receiver fails, the cost of replacing it is between £12 and £20.
The cathode ray tubes are worth about £10,000, the platinum about £8,000 to £10,000, and the valves and so forth probably another £10,000.
It occurs in the manufacture of cathode ray tubes and shoe-fitting devices.
The subject referred is the supply of electronic valves and cathode ray tubes.
The cathode ray tube has no guarantee of extended life.
In the case of the cathode ray tube there might be recurring payments.
The cathode ray tube costs a sum of money which people do not spend easily.
