  1. Paul, I wonder how many hours your BHK 300 get used in music room one every day. I am trying to figure out how soon I should re-tube my BHK 250 and I listened to it about 3-4 hours daily. THx.

    BTW, I really enjoyed all the "ask Paul" videos. Learned a lot from you and thanks for taking the time to do that for all of us. Really appreciate!


    1. Thanks, Allan! The system's on quite a bit and because it's used so much by the engineering group as well as me, and sales, etc. it often gets left on for days at a time without anyone paying attention. I probably should be a bit more strict....
