Oh, a stereo rehash of the old Philco Beam Of Light system. Interesting. Anyone ever come across these, or was it just a theoretical test sort of thing?
Came across one today for the very first time on a newly listed Ebay "Buy It Now".To be honest I purchased it for it's uber rarity,also thought it would look real nice next to my Trio Supreme 1 amp,which came out around the same time.
