Help with a Kora Galaxy tube amp


My brother just gave me a Kora Galaxy 50wpc tube amp that needs some help. The sockets that hold the EL84M tubes are broken.

I'm pretty handy with the soldering iron so I have no problem replacing the sockets and tubes, but I don't know about biasing the amp once the repairs are made. I guess I was a few years too late going to Navy ET school to learn too much about tubes.

Any Kora experts out there that could walk me through a biasing procedure? I hear they're a bear to bias.

Anyone have or know where I could get an owner's manual for it?

I found an article online about a Joe at JC Audio that seemed to know about them, but I can't find any contact info.

Thanks
Jeff

I had a steal lined up on a Galaxy Ref but passed when I read stories of Kora biasing and lack of support. I'd take Steakster's advice and at least consult with Aball.
