Ampere APB-87A 70cms linear

[DX-DIGGER]

Hi Guys,
I am looking for a circuit diagram for an Ampere APB-87A 70cms linear amplifier.
I have extensively searched with google and other search engines but have failed to find ANY info on this manufacturer "Ampere"
I am thinking maybe it is a Japanese company but I am not sure.
Soif any of you guys can offer a source, that would be great.

Thanks Mark
