The car lives on to be enjoyed by someone else.
This isn't an accurate analogy in the case of the radiogram amp discussion. The engine of an old car is entirely specific to that old car (or to others of exactly the same type - and collectors do swap them between those). It would make no sense at all to take the engine out and 'run it on a stand'.
An old valve, on the other hand, is just a general purpose component. It was used in old radiogram amps in exactly the same way that it was used in old wirelesses. If you'd gone into a shop back in the day and said "I need a new PX4" the owner wouldn't have said "What do you want it for ? I like wirelesses and if you want it for a wireless then I'll sell you one. But I don't like radiograms so if you want it for a 'gram then you can sling yer 'ook." That attitude has come about more recently, since NOS PX4's have become rare (=expensive) and enthusiasts have had to swap them between bits of kit. Folks whose hobby is limited to one sort of kit don't seem to be happy when the valves are used by folks whose hobby is another sort. Since there aren't enough valves to go round even the vintage kit however, some of that kit is going to have to do without. The debate can then boil down, sadly IMHO, to us arguing that our hobby is somehow worth more than other people's.
The question of putting old valves into new equipment is a much more contentious one. (Even the car enthusiasts did it though https://en.wikipedia.org/wiki/Rolls-Roy ... ative_uses
.) Personally I might go as far as fitting old valves to replica old equipment, but I wouldn't fit rare ones to new designs. I'd hesitate to judge other people over that though. I would also absolutely condemn anyone who threw an old wireless, minus one or more valves, away, rather than letting it be enjoyed by an enthusiast. That said, if the enthusiast wouldn't want it unless it had all the original valves in, then I might raise an eyebrow at him too ...
