But wait....there's more!

May I direct you to J.B.Calvert's site:


Note the magic words, "Every circuit has been tested in the laboratory".
I have built a few of his circuits and they perform as described.

Chapters 12 and 29 are especially relevant to tube fiends.

As a bonus, many of his circuits use TV/radio tube types which are
generally unloved and thus can be bought quite cheaply.
