Thanks to you all. Not sure which I'll use to refinish. It'll probably be based on something practical, like which of the two (or three) products are carried by the store I frequent.
Also, thanks for the info on year of production. I was kind of guessing based on the timeframe of attendance at UW-Milwaukee. Bought them at a good old fashion audiophile store, Flanner and Hafsous (Sp.?} in Mayfair Mall. Used to enjoy going there and wishing I had some money. Recall the speakers cost about $600 for the pair. I see the new heresy's go for $1,000 a piece.
