Tube Amps Links...

[monthlymixcd]

Duncan Amps now has their Tube Data Sheet Locator tool on the web:
http://tdsl.duncanamps.com/tubesearch.php
It is invaluable if you are building or working on tube amps.

They also have many schematics for vintage amps posted for download:
http://tdsl.duncanamps.com/schematics.php
More than what you'll find in the Aspen Pittman book actually...

This Dave Hunter book is a great read for anyone that digs tube amps:
http://www.amazon.com/Guitar-Amplifier-Handbook-Understanding-Amplifiers/dp/087930863X
... his effects and guitar modding books aren't bad either.

For anyone working on vintage Fenders... get to know the Gerald Weber book series and DVD:
http://www.amazon.com/s/ref=nb_sb_noss?url=search-alias%3Daps&field-keywords=gerald+weber&x=17&y=21
I have them all and they are all useful... and at times really funny!
