Howdy;

I'm working on an Awia CX-NDS15U CD/Tape/Reciever entertainment
system.

The problem is, System will run fine with the volume all the way
down. if you increase the vol. above 12, the unit powers down within
3 seconds.

You have to wait about a minute before she'll let you turn it on again.

It may run a while longer at lower volumes (I ran it for 1/2 hr without
a shutdown at volume 5)

Does not matter if speakers are in circuit or not. It behaves the same.

There are 2 2SB1370's on the main heatsink that get hot quickly.
If I spray them with freeze the unit will keep running until the heat up
again.

I really need a schemo on this to see what these 2 guys do.
Their collectors and emitters are are paralelled together.

I've check for bad or leaky components on that board, but have turned
up nothing. The owner's hot for having his stereo back, so I'd appreaciate
any help with this unit.

Much thanks,
Rick

Damn. Now if only someone would make some Aiwa PDF's available.....
