Title: Blues Jr Schematic VS layout
Post by: Room335 on January 12, 2023, 10:05:13 pm

Is the 1n4007 backwards on the layout VS the schematic?  see attachment.

My first build - I know I should have started with something simpler but my Blues JR had some serious issues so I started from scratch. Thanks for your help.

No, the documents are correct
The diode is making negative voltage for the bias circuit
