Antique Sound ASUSA A-8 80 watt audio tube amp kit

Hello, I'm looking for information of a USUSA a-8 80 watt audio tube amp kit. It was made by Antique Sound before they got bought out and the new company has no information on it. I have this kit but it missing the paperwork instructions parts list. I believe the kit is their with the tube , caps etc but I not sure of the procedure to build it. If you have the manual or might know where I can get it plaese let me know, also if their is another forum I should try. Thanks for you time.
