Single Ended Triodes (SETs), the ultimate tube lovers dream.

Re: Terraplane Buzz

Did you build them yourself?

This is wild speculation, but the only thing I can think of is that the Power Supply rectifier diodes are buzzing, which is normal, but with the chassis closed shouldn't really be audible. If somehow this buzzing vibration is being transferred to the top or bottom plate and causing it to vibrate in sympathy then it may be audible.

If you think this might be the case then mechanically decoupling the PSU module from the rest of the chassis with rubber washers or grommets might be the remedy. I'd be wary about any damping to the diodes themselves though because they need to be able to dissipate heat effectively.
