Hi roxy54,
I did give them a preliminary listen to check to see if all the drivers worked. I had heard from some other folks that it was very common to find the tweeters and/or midranges nonfunctional due to an electrolytic corrosion problem between what they said were aluminum voice coils and the external interconnect. I don't know if that is true, but all drivers seem to work. My first test was a quick hook-up to a Pioneer SX-1250 I am restoring that I bought at the local pawn shop for $29.99! It was cosmetically beautiful and complete, but had a nasty 60 Hz hum on just the AM and FM inputs that was quickly diagnosed and repaired. They have a very 1960's sort of sound to them similar to the Harman Kardon HK-50 from 1969, but with more punch and power handling capability. I also want to check the crossover components as they are 50 years old now. After I complete the cleanup and spider web/dust bunny removal, the plan is to hook them up to the equipment I'll be using them with and give them a thorough listening too! So far I have been very pleased with what I hear. In addition, I really like the cabinet work and styling of the fluted column. I'm hoping that I might find the optional marble tops somewhere in the future as I think they would make these systems look even better!
