It may be a mission getting hold of a set.
[OK, I just couldn't resist]
I can see that. They seem to be very old speakers and very well loved...
I'm still on a mission to get some speakers. The reciever was delivered this morning, so Now I'm going home with nothing worthwile to connect to it.
At this stage it looks like I will connect my cheap sansui 40watt speakers, and just play them on the low end. I do not want to damage the amp yet. (those sansui's are 4 ohms)
