Hollow-State Design – Blog and Book

For those of us who did not grow up with tube/valve/Thermatron gear:

Hollow State Design

Links to the Blog with links there to the book: Hollow-State Design.

Presently about 1/2 through reading my copy,  and finding this an excellent book!

Got my copy from Electric Radio, but you can get it at 20% at the moment ordering directly from Lulu.
