From approximately the late 1950's into the 1970's, audio equipment pioneered by Avery Fisher and sold under his name, was considered some of the finest available.
While many enthusiasts consider tube driven equipment as the acme of performance, in the early 1960's, Avery Fisher introduced one of the first all solid state control amplifiers with the Model TX-100.
The unit is fully functional (disclaimer: the only input I've been able to check is the phono, but I have no reason to believe the others exhibit any problems). All stenciling on the front is intact as are all the knob covers. The original case is included, although t is a small chip and a few marks on the top (see link provided below)
The unit and packing weights 30 pounds and will be shipped at a cost depending upon your location.
Also included are the original Operating Instructions Manual and Service Manual.
Please ask any questions and request any necessary photos before bidding.
Good Luck and thanks for looking!
