I have an Allen Organ Custom Stereo. I can't seems to find out any info about this. Does anyone have and info on this or know what years Allen manufactured these. It is an Allen Organ Mod# Stereo, Serial# 211. It has a 350watt Coronet receiver in it that was made by Harman-Kardon Inc. Mod# MX601/MX800. Any info would be more than I currently have. Thanks.
