Nikko Alpha 1 Amp??

Does anyone have information on the Nikko Alpha 1 amplifier?? I have the chance to grab one, but can't find any information on it. All I can find is that it was built in mid 1970's and is apparently 230W/channel stereo. Lots of info on the Alpha 2 and subsequent models.
I guess you can grab this one for around $150?
It's a good bang for a buck. The only thing I don't like about Nikko is the output transformer otherwise it's good budget take-point.
