I bought mine used but it was supposedly sent to Lamm for a full re-tube - I listed above what it came with. Just curious :-]

I am thinking of getting L2 but I am concerned of frequent tube replacement. What is your experience about this and how do you know that tubes need to be replaced - by sound ( dull, lack of high frequencies, ?) or inability to maintain 350V on test points 115 and 116? Thanks
