Hughes and Kettner amp and Ibanez cab

Hello,

I have recently been looking for an amp and i found somebody giving a Hughes and Kettner warp 7 transistor top and a 4x12 ibanez cabinet away for free.

The only issue is that the overdrive channel is defekt and the cabinet has a loose speaker.

Is this possible to fix for a reasonable price? And is the sound even worth it?

Thanks beforehand!
