I have a really nice 961 PS. I can see no scratches, dings, dents or nick.... Overall it looks like a 9+. Output is a steady 13.8 VDC. Ten-Tec gives a $115 trade in for these so I will sell it for $115 plus shipping. FIRM. Money order requested. PayPal can be arranged but will cost slightly more. Jerry, KG6TT Fairfield, CA
