I own a Johnson JT50 Mirage. I like this amp but it is in a great need of some repair work. I read the thread posted on the 10th of August 2010 by Edwardeffect1 with great interest. Joecool85 suggested the site http://www.johnson-amp.com/support.htme. I know that Johnson Amplification is no longer in business but I still tried the site but it does not load. I would appreciate it if someone can help me with acquiring the schematic.
