From my own humble experience of once removing white paint from a set of AR 2ax speakers, I can only begin to imagine the effort that went into restoring that Barzilay back to its original condition. Very, very few would want to tackle that job.
Seeing that beautiful cabinet also triggered an experience from last year. An estate sale in NH (about 2 hours away from me) featured a Barzilay cabinet much like yours, plus the same lattice speaker cabs, for I think something like $300. (The electronics inside were solid state and pretty ho-hum.) On the last day of the sale, the price was down to $150. I called the day after the sale ended and was told that the Barzilay went unsold. Did I want it? I could have bought it for a song but just couldn't swing the logistics.
It still makes me feel a little sick to think about. :tears:
