What are the specs for Kenwood KA-89 and KT-59?

Hi,

I haven't been in the forum for years! But I recently got some old (late 80's?) gear:

Kenwood KA-89 Amplifier
Kenwood KT-59 Tuner

They seem to be nice. But I cannot find any power specs for the amp anywhere. Does anyone know about these?

Thanks!
