Truthfully, this one is NOT pristine, perfect, stunning and all the other words used to describe things here on Ebay. It was built in 1962-63 and shows some age. The chrome on the backside has corroded and pitted some. But, it works right and sounds wonderful. Some time back, a crossover capacitor and a potentiometer were replaced. I have already packaged this for shipment, so I am not going to be able to tell you much more than you can see in the photos. This was something I intended to keep forever, but hard times have fallen on my family and I must sell. Again, not perfect, but very nice! PLEASE READ THIS - Continental US buyers ONLY! I do not wish to deal with international shipment. Thanks for looking.
