Peavey is one of the most customer friendly companies I have ever done business with. If you email firstname.lastname@example.org
they should send back your drawings if the ones above are not what you need. Include the serial number of your amp to make sure they get the right drawing.
Also, if you need specific assistance in the repair, you can talk with one of their service engineers on the factory repair forum at www.peavey.com
