High pitched noise from Blues Deluxe when playing certain notes on Rhodes

[alexdecker]

Hi all

I just got a hold of a Blues Deluxe Reissue. Its wonderful, but when I play the note D#3, and sometimes the notes surrounding, the amp emits a high pitched noise. Often I can only hear it when the tubes get a little warm (within 5 min or so).

Is anyone familiar with this problem, and what could a solution be?

Take it back and have them check it out!

Might be a microphonic preamp tube, they do that at certain frequencies.
