Hello folks!

Recently purchased a WORKING '86 alpine 3533 amp that supposedly pushes 120w, and goes down to 2ohms. I have a single 12w6 in a sealed enclosure to power it with. Intended for home use. Just want to test this thing out, see if it works. The sole problem is the 6 pin connector on it.

Refer to these pictures, mine is identical; which pin is positive, which is negative and which is turnon ?

Any help would be very much appreciated!

Ok... here's an update.

I took the cover off, and have discovered the following:

2 pins on the right are bridged, and go with yellow wires through the 30a fuse; -- these are clearly power, since they proceed from the fuse to the power supply section. Next, there are 2 pins on the opposite side, NOT bridged, going to the power supply.

Lastly, there are 2 more pins - a blue one in the middle that goes to the main logic board, to a spot labeled I8, and a red one, going to a single 3a fuse, coming out as a black double cable - one part solid black, one part black with a solid white line in the middle.

Should i ground the blue wire to turn the amp on, or short out the red and blue?

Please help!

Opened up the power supply unit... had to unsolder the tin cap.

Wowie Looks like a monkey did it. Cold solder joints everywhere, some things are barely connected, many pins are left unclipped.
