Thanks, I apologize, i should have been more specific...

This is on a D'lite.

I'm talking about the 1.8k resistor across pins five and six of the power tubes.

Thanks!

Can anyone explain to me how changing the values of the swamper resistor affects the amp?

Thanks

I looked over the Marshall schematic this week. It is exactly the bias circuit option that i needed. Thanks.

Do i need to use a voltage divider to get 45v, or can i pull straight from one leg of the transformer as Marshall did?

Thanks

thanks guys

Guys, This is my first post, i normally just read. I'm building a d'lite from a normster layout. I ran into a dilemma that was caused by stupidity on my part. The transformer that i ordered does not have a bias tap. I never noticed. The bad part about all of this is that i never noticed until i had ...
