I was wondering if someone could help me out...
 
This may not be an appropriate question to ask here, but I thought that someone at this forum may have an answer for me.

My wife wants a stereo for our kitchen and I was at a thrift shop yesterday and saw a kenwood KR-A48 and thought it would be a cheap solution. I have two 8ohm 100W KS-401HT rear surround speakers I was going to use with it mounted on the wall. I have never used them but I'm sure they work...

So my problem is that I hooked up the receiver to an AM antenna and some random HTIAB speaker to see if it worked at the shop and I was able to get a station and sound worked out of the L and R for speakers A and B. Then I get home with it and I can't get any sound at all. I tried all the inputs and the radio. The headphone jack works with the volume dial for all the inputs. I'm not sure if it's amplified or just applies resistance to the signal.

Does anyone have any quick suggestions to what I can do to make it work?

I can't find anything under that model number on google or bing !

Is it a normal receiver with normal speaker sockets ? Picture of it maybe ?

If headphones work then thats usually a sign most of the circuitry is OK. Question is whether it has a normal output stage or not, and not finding anything on the model I wouldn't like to guess.

Sorry! it's KR-A46, not 48.

Here are some pictures.

All the capacitors look fine and I couldn't see anything out of place that would cause a short. The fuse also looks fine to me. To clarify, when I get no noise, I mean not even hissing.

Did you activate the speakers with the corresponding pushbuttons A or B?

Even if it is working as is, it would be a good idea to clean the dust from the innards.

As above really re the speaker selection.

I would guess that this uses the main power amps for the headphone feed so I would say basically all working.

Yes I pressed the push buttons for both a and b. I am really at a loss as to what could be wrong.

Most probably, the headphone socket has a dirty/ open contact. Just try pushing in and out, the headhone jack.

Some receivers series the A and B speakers, so if there are actually no B speakers, you will get nothing if you switch A+B.

From another angle... are you 100% sure your two speakers are good ?
