How is this possible -you say tubes can vary 'as far as amplification is concerned', but 'it doesn't influence the sound'. This is impossible.
A pre-amp tube amplifies the low impedance guitar signal, and shapes the tone. Pre-amp tubes are the most important tubes in you amp when it comes to the 'tone' of your amp.
The power tubes amplify the signal from the pre-amp tubes, and tubes from different manufacturers and even different batches from the same manufacturers do this all just a bit different. Some tubes amplify the bass just a tad better, some the treble frequencies a little better. All power tubes add compression, but some do it in a more musical way (RCA 6L6 anyone), some in a really irritating way. Some tubes add dimension to your sound -vintage tubes have a 3D sound that to this day is not replicated by any new tube yet.
Manufacturers have always constructed their tubes in different ways. Just by looking at the materials and construction I can tell the difference between a Philips, RCA, GE, Svetlana and Tung-Sol 6L6. And, placed in my own Boogie, I can pick out each and every of these manufacturers blindfolded.
