They had different "FETRONs" for the same tube operating under different conditions like with an amplifier versus an oscillator.

I'm not sure I understand the reasoning.  For example:  say I have an old 300dpi document that I used to print on my 300dpi laser printer in the past.  Then today, I choose to print it on my brand new 2400dpi laser printer...  the document will look the same (still 300dpi resolution), and I will not have incurred greater cost for the fact of the new printer being capable of much higher precision - paper is still paper, toner is still toner, etc.? 

This is true even if the new printer is much more expensive than the old one.  I guess if you write off part of the cost of the printer on each printout, you could get uneconomical results compared to the old, written down printer, but that seems more of an accounting technicality than a real cost?

in this case : your 2400 dpi printer is 100 times more expensive in purchasing coast and 20 times more expensive to run than your old printer.
The paper you print on is also 30 times more expensive than your old paper.
on the other hand : the upgraded technology can print in a font 150 times smaller than your old printer. you sell single letters ...

what do you do ? printing in 300 dpi costs 60 times more than with the old printer. on the other hand , if you print in the new smaller font your costs are half. the drawback : the new , smaller letters don't work to replace broken letters in the old fontsize.
There is no reason to keep printing this old stuff. the newer letters are more profitable , and they allow miniaturisation of the end product.
