This listing is for the 12v power supply I used on my home entertainment center until very recently with  a Pioneer mobile EQ  that was bought in the late 1990s. 60-day Ebay used-item functionality warranty included

The power supply is in a wooden from the 1970s and came from a hybrid  mobile/home entertainment setup allowing the in home use of a high-end under dash car receiver. I believe the brand was Awia. it was made in Japan. the unit slide in and out of a mount in the car and in and out of this power supply.The old car unit no longer exists. The power supply  has been modified for mounting and use by the graphic equalizer.
