    japanese tubes

    Thanks for identifying the make of these tubes They definitely sound better than the new JJ's I am trying, the Matsushita's have more clarity and depth and will definitely be put back in after a while, The two 12BH7A and the single 6AQ8 look like they might also be the same make but the 6L6GC's...

    Show Me Your Sansui!

    What I did was just throw the budget out the window and went for it. So far it has been very expensive and worth every penny.

    Show Me Your Sansui!

    Everything that has been said about the voice of the AU-111 is absolutely true, currently I am abusing my bankbook badly buying vintage tubes to see if there is room for improvement. We will see if there is.
