Pioneer KX-444
« on: March 22, 2021, 08:19:04 PM »
I got given a some Pioneer kit by a family friend. The only thing that intrigues me is the amp.

Does anybody have any info on the KX-444? Iím going to test it on my Corals soon, but would like to know what kind of power to expect.

Amp is really neat with hardly any scratches. Will post pic of it open soon too.

That is the same as my dad's old unit. IIRC it is rated at 13 watts, but with a whole 2% distortion. I remember it used to hiss audibly whenever you turned it on. Great sounding, but not the quietest around.

Thanks for that, Deon.

Picked up te receiver today. Its very clean.




Then I pulled the lid off to see how much cleaning it needs.



To my surprise I found no dust inside! What?

Then I pulled of the bottom cover to have a look at the business end:

The cover had the most dust on it^

The rest looks like this:







Its unbelievably clean inside. Shocking. Now its going to be to see how the caps like power.

Apparently this thing hasnít been switched on in about 25+ years...

Let me close it up and power it on.

Powers up with only one light. 
Will fix that later. I need to find some lugs somewhere to make some terminals to connect some speakers up as theres only one that came with it. Lets go scratching...

Running braai music through it. Sounds good with the corals. Enough power. Ignore the horrible placement though. WAF.

Amazing that this played "out of the box" after 25 years.

Enjoy that Vintage sound, there is simply something special about the quality of sound reproduction from the older generation audio equipment.

It is beautiful with all the lights working. A "baby McIntosh" look with the blue lights and gloss black. I still miss my old kx-444. These older low-powered receivers don't generate much heat, so little venting is needed - one advantage is little dust gets inside. The cool weather inside that case is good for all the components too. Enjoy that lovely, easy sound.

I did some Ďresearching and it seems the kx-444 is essentially a sx-440.

The manuals specs on power output:

Iíll see what I can find for replacement LED lamps, otherwise just make some up.

So the lights all run off a 7.5v AC tap.

It runs 3x fuse type and an e10.

E10ís are easy, anybody know where to find 8v fuse type? Or should i just try 3.5w 12v festoons? Although these might burn to hot?

Other option is to fit all e10 lamp holders.

Try the festoon LEDs, they will not be that bright on 8v.
