Hi, just picked  up a 

Welborne Labs Laurel 300B vacuum tube power amplifier on an auction....being sent to my tube guy.....do you have schematic.


thanks

Boy I could sure use a diagram for the Welborne 300-B amp.....I'm not having much luck on this one.........I gave Welborne Labs three chances to sell me one but they won't return e-mail or phone calls......Maybe I should change it to a Assemblage 300-B amp...
