Eddy1 - sorry to hear that you are not happy. The Rogers - so far - is dead quiet. I've not owned a CARY product, but the noise you are describing doesn't sound "normal" for a fully functioning tube amp. Did you buy used or new?
Hopefully someone else may be able to chime in that has more experience with CARY products.
