Tubes that "aint quite right" can cause a buzz, but sounds like you have already rolled 'em so guess thats not it.
Jolida JD 100a - help w/Buzz when using headphones
I recently purchased the Jolida JD 100a and discovered that the CD transport mechanism, particularly when it spins the CD, is audible as a "buzz" in my headphones (Sennheiser 580s). It is also audible from the player itself. Is this normal? Or is this a defective player and/or correctable with lubricating the mechanism? Help.
