Default Kenwood 4070 Stereo Receiver

Hello,

I think the power rectifier is out on my receiver.

I found a NTE5312 rectifier. Does anyone know if this
can be used as a direct replacement?

Also, where can you get manufacture
replacement parts for this receiver?

Regards,

Terry

Kenwood parts can be had from East Coast Transistor Parts, 800-645-3516.

Many parts for this model would not be available, since it's about 20 years
old, but Kenwood is pretty good about parts availability.

There's an excellent chance your rectifier could be replaced with a generic
type, but I've no idea about your NTE sub. What is the purpose in this
circuit? Is it a good physical replacement? What are the NTE specs? All
these should be considered. Techs make these choices all the time. DIY and
shade-tree types may be more prone to mistakes.

Before you jump through too many hoops here.....
do you know for certain that the "rectifier" is "out" ?
Have you tested it ?

Power rectifiers usually short, causing the main power fuse to blow. Once
in a while a section of a bridge will open and a hum will be heard in the
speakers. If you are in doubt about the rectifier being bad, it is
probably okay. Check the plus and minus voltage at the large filter
capacitors to ground, if they are equal, the rectifier is okay. If you
need that rectifier though, just replace it with something having a higher
amp rating, and at least 200 piv, the higher the better. Very few items
in that receiver will require a Kenwood part.
