The pre-II was an excellent pre-amp with a very acceptable phone section. Its age however is somewhere around 15-20 years old. If it is in good working order it is probably well worth $150. I was the Electro Importer in the mid to late 80's. when I owned Music & Sound Imports. Have fun with it. When they worked they were great. They did have some problems with noisy volume controls.
