Yes likewise it is a nice sounding pre. The Nutube in my build is cushioned by some soft rubber which is the red stuff you can see under the Nutube. A sharp knuckle rap on the case causes sound through the speaker but it only lasts a second.

That is normal for an effect generator

Default A Nutube based I/V stage

Hi,


Congrats to this great project and those of you who've already built it. I definitely plan to do one myself.



While on the subject of Nutubes, I have one of those niggly ideas that wont go away.



I would love to see/hear a Nutube based I/V stage for the likes of RyanJ's 1541, Ian Canada's Fifo/isolator/dac boards or as a simple single board to install in various spinners and Dac's/



I have a feeling this would sound gorgeous and could turn into a really great little project / Group buy.


I'm fairly new to diy Audio and am not quite at the stage yet where I could design a circuit or modify an existing one but I'd be most grateful for any assistance or to see someone with the skills bung out a quick circuit to breadboard. This would be a fairly simple circuit no



With thanks,

Sylvain thank you for making the boards available. Also sounds excellent through headphones.
