[quote author="kent"]Aaaaarggg! I used to have a link to that Spangenburg textbook which would be a great resource for you but I lost it, and a bunch of other links, after a hard crash. Does anybody else have that for him? I'd email my copy but it's HUGE!

anyone?

Morgan Jones' "Valve Amplifiers" book is an excellent resource:

This has a nice section on how to ground circuits to avoid hum. Since I've adopted the techniques mentioned in the book nothing that I've built hums. :thumb:
