I will take a crack at in. I have seen pristine ones go for close to $2,000 but they look almost like new and don't need any work and the tubes have all been tested and there is a lot of life left on them. But, you need to see what version yours is. The ones I spoke of above were for the "Z" version. Take a look in the serial number and look for the "Z". These are the ones most in demand. Most will go in the $1,000 to $1,300 range for a very nice one. There are usually a few available on ebay. Search for "110Z" in consumer electronics and then look at the completed listings to see what others have sold for. There are many folks on here who are much more knowledgeable on this model who hopefully will chime in and shed more light for you.
