Sorry, I didn't get back with you on the Riders. I bought my tube sub guides from Gary at PTOP. He has an extensive list of tube manuals and sub guides for sale at very reasonable prices. Obviously you have found the tube pinouts at NA. Another good source, if you haven't seen it, is http://www.nj7p.info/Tube.php for looking up tube data. I agree with you if I had a 116 I would convert it back to original also. Good Luck. John
