Schematics and Layouts / Yamaha JX20 Service Manual
« on: May 30, 2019, 02:28:45 PM »
I just pulled my 1981 Yamaha JX20 amp out of the closet for the first time in decades. Playing around with it a bit and would like to mess with the circuits a little and retro in a digital reverb etc. Looking for service docs/schematic, I've been Googel'ing for a spell and haven't got lucky yet. Found the owners manual and service docs for a JX30 & JX40 (those may be close enough).

Does anyone have a JX20 service manual or have a link to one in an archive that I haven't found yet?

Thanks,
