Just curious if there are any issues with external noise using a non-shielded chassis.
Actually, I posted about this issue at TGP prior to the build. Adam Grimm of Satellite Amps said the following:
You can build it on a wood chassis if you have to. Some chassis don't shield very well anyways. Grounding will be a concern, but it can be dealt with. I wouldn't bother with copper foil or shielded paint. If it was me, I would use a large brass plate behind the controls to act as a grounding bus for them. For the tube sockets & transformers), I would probably use a piece of plate metal (aluminum or steel) and cut it to size, then punch holes and mount it on top of the wood chassis. I would then use a large wire to connect the two together so they are one common grounded plane. Use wood for the rest.

Also, some folks posted photos:

And then I found that audiophiles reverred wood chassises in some circles. And I got the following response from another board:
Considering how poor the grounding is on the original and how the chassis can not work as a shield because it is a current conductor, I would say if he uses a modern grounding scheme then it will be better then original.
Anyway, I took a risk and it worked out. I'm not having any shielding issues.
Thanks for the welcome. And I'm open to suggestions for the next project!
