I have just listed some Ten Tec amplifier parts on Ebay UK. Go and have a look. Happy Easter to all who celebrate!
Check out Zach’s project: http://www.foxtango.org/phpBB2/viewtopic.php?f=1&t=1493&p=3545#p3545 I have done this sort of thing plenty of times. Maybe you can help him out with advise and parts. Good luck Zach!
