Nestorovic Owners

Please contact me if you own or are interested in these wonderful components. We all benefit from each other's tweakings.
I have Nestorovic 5AS speakers, t-cabinet. I bought them in the late 80's. I still love them as much as ever. What's up?
I´m looking for a pair of NA-1 Monos. If I find on in the USA, is it possible to covert them for 230 Volts?

Best Regards
