Title: Marshall 18w Lite w/6V6; check for errors and suggestions
Post by: sawdust on November 19, 2008, 04:03:31 pm

This is my first attempt at drawing a schematic. I took an 18w Lite and changed the output tubes to 6V6, I changed the components to match a 6V6. I think I have it correct but can anyone look and comment, and make any suggestions on component selection.  I included the version of schematic I used to copy from and my version and a gif version. I used the new Jschem to create the schematic. The bias circuity is tapped off a 50v wire on a Fender xfmer I am going to use. Thanks.

You'll need to change that 100k bias resistor to something like 470-1000 ohms.
