Up for sale is a classic Pioneer SX-3700 AM/FM Stereo Receiver from the sought after Fluoroscan era (circa 1980 to 1981). 

I acquired this unit directly from SG Custom Sound, a well known specialist audio repair shop in Queens, NY back in 2021. They professionally serviced this unit and is 100% full functioning. I primarily used this with my Pioneer turntable.

I've had this in storage the last 3 years, in near mint condition.
