I am looking for a schematic for a citation 19. I bought them when they first came out. I was stationed in Okinawa and was friends with the JBL rep. They were troubled amps from the very start, bad outputs, burnt out LED,s bad filter caps.. I bought two amps at cost, but now am surprised they were repaired ones! Over the years I don't know what happen to my schematics. I had one go out recently. I was so surpirsied someone had repaired this one with sub transistors. They used the MJ15003 and /4 and ERS60 /1 for outputs. I can not belive they would use the MJ's and ERS subs in the same bank. Unbelievable. I am able to find the MJ transistors. At the beginning I did replaced the LED's and filter caps and they have worked really good over the years. The ground between the caps came off and blew out my outputs, hope nothing else is wrong. I am still in need of a schematic though. I am presently an electrical engineer and have serviced audio equipment and built my own amps over the years. I built a mosfet cit 16 and it sounds great. Any help in finding a schematic would be greatly apprecitated. I am new to this forum and hope to be part of it alot. Found some great info here. Not compeletly sure how to navigate the site, but am learning.
