thanks again for your posts. The photo of Larry's speakers served as my inspiration.
I was able to replace the electronics in the NLA's. I refoamed and gave them a listen with the old stuff and they sounded dead. One worse than the other. Then the new caps and resistors and the speakers came alive!
The only piece of equipment I have that might have been of their vintage is a small Marantz 2220b receiver, I think like 20wpc. Believe it or not they sounded pretty good with the little receiver.
I was going to sell them but I think they have been granted a reprieve.
