Hi dtaylo3
I had the same problem as you. Due to microphonics I found myself flying through the room to save the tweeters of my loudspeakers.
Had fixed the nutube with doublesided tape. I was about to throw the project into the dustbin. Then...
1. I remembered an early mail from N. Pass who had fixed the nutube with hotglue to the pcb. UUHHH - not at all audiophile. I had nothing to loose. I could not remove the doublesided tape but I fixed the nutube with hotglue.
2. In 1-Euro shop I bought a plastic container for food and mounted the nutube inside. No rubber washers, just solid screws into the wooden mounting plate.
The result? I can tab - no I can drum - with my fingers on the plastic container. Nothing happens. No mycrophonics, no tapping sound from the loudspeakers, just music.
And the sound? I have a Khozmo shunt passive attenuator which sounds very clean and precise. With the B1 Nutube the sound transformed into something new and juicy. Never thought this thing would sound that good.
Give it a try!
Hi,
Do you have actual pics of your build (nutube cover)? I'm curious how it looks, as I can't imagine how it looks based on your description alone.
