Wright WPL10V


When in phono the preamp box itself is sensitive to the touch. I can tap it with my finger nail and hear it through the speakers...new tubes? Thanks for any help!

Sounds like you were in here listening to it too! Already ordered tubes and the highs you mentioned are spot on. Thanks very much for the reply.
One or more of your phono section tubes has gone microphonic. I have a WPL20 that exhibits the exact same problem when one of the phono tubes goes wonky. Tap each with the eraser end of a pencil with the volume set low and you will hear a hollow metallic bonk when you hit the bad one(s). You may notice that your treble is less peaky at high levels once you change out the problem child.

Good luck,

Adam
