Kenwood Ka-770b
Hello,
i have an KENWOOD KA-770B amplifier with a problem . Some of the transistors from the preamp module have been "blow" ,I have search over the internet to find a schematic for this amplifier but I didn't find anything ....th original amplifier module's have been replaced with bipolar amplifier kit's , about 200w each one . If anybody have some schematics I would be grateful.... sorry for my english. |

Without people who collect, collate, and offer the manuals to us, the hobby of vintage audio dies.
Consider it an investment in the health of the hobby, and in your education. If it is worth fixing, it is worth buying a manual for. |
