I had a brochure for an Aragon amp back in the day. Is this one of the ones with the "V" cutout in the top? Those amps looked pretty awesome.
I guess being as old as it is, you should check it out to make sure both channels are fully operational and that transformer hum hasn't gotten out of hand. In my town we do not have a hifi repair that can install new parts but I would think if you had local access to a person like this - this amp could represent a good value at this price.
