[QUOTE="Rilke, post: 157081, member: 3746"] I have done the exact same thing with another of my amps, a 71 Fender twin reverb, where I changed to NOS tubes over JJ's. The difference there was greater (I felt that it was much more musical and 3d sounding), but I did not record the differences so it very well might be imagined. The brain is kinda the enemy here, because we just want/wish the sound to be better with the NOS tubes, it is easy to 'hear' a big difference, especially without a pre/post recording. However I've been through a couple of powertube combinations with the RM100 (recorded), and there is a markedly different sound with EL34/6l6/KT88's. I have promised a video documenting these differences but never got around to making it. I will probably get around to it soon though. With the high-gain sound I would have loved the NOS tube to shine through, and it does sound a very small bit different (a bit darker/warm). As you say, though the diffence, at least what this particular sound is concerned, is so small that nobody would notice it, when I listen to it, I would say the sound is basically unchanged. [/QUOTE]
