Hey guys.
I was at a local parts store this past weekend, and the guy behind the counter knows me pretty well. I brought in my poseidon amp, and he asked what the tube compliment was. Then he came out of the back room with 4 NOS Amperex 12AU7s. He gave them to me and told me to take them home to see if they worked. I did so. First thing I noticed was that they "flash" when first energized. They say "Made in Britain" on them. I can only find orange globe information about these tubes from Asia and Holland. Does anyone know anything about them?
They sound very nice, and what I'm finding is that they run between 25-50 bucks for NOS tubes of this variety.
I read about a half moon shape cut out of the plate being the difference between the Asian tubes and the ones from Holland. Mine have the holes like the Asian plates, but flash like it says the Holland tubes do.
