But what has all this to do with Tube/Valve amp Noise???

I have found that a gunshot is extremely difficult to reproduce. The
spectrum is roughly 10Hz - 40kHz, with low caliber rifles being more
towards the high end, and large caliber pistols or shotguns being
somewhat more towards the low end. Further, supersonic projectiles add
yet more "color" to the reports. The entirety lasts about 25ms but
depends on several factors, a very brief moment.

So, if you can get a combination of microphone, recording medium,
amplifier and speaker that can do this with some accuracy, that is no
small thing.

Further to this, anyone exposed to a variety of gunshots will never be
fooled by a backfire, fire-cracker or similar devices. Even blank
rounds sound quite different than real shots for a variety of fairly
obvious reasons. There are exceptions, of course - sub-sonic rounds is
one of them.

So, there is some link, however remote.
