Line 6 Duoverb Amp

[Bob W.]

Good afternoon all. I am looking for a Duoverb service manual or just schematics. Probably can get away with switching power supply and amp section. Thanks, Bob

Here it is. The SM is too big to post it all at once. Let me know if you need more.

Really appreciate the offer but both links came up "Invalid attachment". I've not uploaded anything yet so can't tell you how to do it. Thanks for the try. Bob

I'll try again

And the amp

I'm able to see this one only if I'm logged in. I don't understand...
Why no thumbnail?

Perfect, nice to see what the parts I found bad go to, thanks. Any chance of getting one for the amp board? d13 was bad and and it feeds something in the amp section. Later I may need a test procedure but until I can turn on the amp wouldn't do any good. thanks again, Bob

dmeek, Again just what I needed. Found all the bad parts, I think so anyhow, now need to find and order them. Line 6 is really hard to work with, they won't supply info or parts unless you are authorized. Thanks again.....

I did find something I don't understand tho, hope one of you smart guys can figure it out and let me know. On the PS board, in the secondary section, D13 was burned, both caps going out ok. That pin, pin 6, on the amp board doesn't go to anything. That voltage is not used anywhere I can find. I checked the boards and the pins are just as the schematic shows. My biggest puzzle is why did it burn? Bob
