Thanks!

Yes, this looks more or less identical to the same circuit on the 35 and other classics.
I'll hook it up and try to verify the components and hopefully find what is wrong with my unit ...

Have also been looking for Duells schematics for the 80 but couldn't find it either ... someone have a working link?

Cheers,
Thomas
