Hey there! Regarding the Tung Sol 12AX7 - I'm only finding the soviet knock-offs Tungsol 12AX7 - is that what you used to mod the Blackstar HT5R - or did you score some actual NOS tubes? Thanks again for the tip!
Oh that's awesome! I do remember the Prague Castle being incredibly beautiful, but it had a quite eerie feeling about it. The clock tower also gave me the creeps when I was around it haha although I never cared. I didn't it was supposed to be haunted. I'm not a believer myself, but it's still awesome to hear some of these accounts.
Just so I don't derail the thread, I'll ask here: which winter was it that you went to Prague? It was also 0 Fahrenheit when I went! (-17 C) It was stupidly cold. I think it was in 2009 that I went there.
