@hypnos1, do you know which type of tube was the white base Psvane that FA used on the Elise? Also, given your past experience with the Psvane CV181/TII, can you offer any opinion about the sonic differences @Aornic heard between the Elise and the Euforia ? Basically, what I'm asking is whether the tubes used represent a certain 'preferred' flavor FA likes to give to each particular amp, or are simply the best they could do for each amp's stock sound.
Hi angpsi.
Ashamed to say I didn't even manage to closely scrutinise the different tubes they used during the event. I was under the impression that Elise (as option) and Euforia use the same clear glass PsVane 6sn7, which I'm afraid I've never heard. But the grey glass, gold-coloured-base tubes appear to me to be the CV181 TII, which I believe F-A originally thought was actually not quite as well suited to their amps as the cheaper 'standard/UK' 6SN7 version. I suspect this might be down to the slightly "lighter"/less full-bodied presentation of the TII. Given the (IMO) broader FR coverage of Euforia, this might possibly explain the use of the TII in it at the show...or at least for the short time I myself was there!
