Kenwood KR-4600 receiver

Post by DasherF » 18 Oct 2018 13:19

I acquired a Kenwood KR-4600 receiver a while back from a customer that said it didn't work, but I was happy to give it a good home. Got it home, plugged in and powered up...no power...any suggestions as to what it may be (besides "dead")? Any hope? It's too nice looking not to work.

I have a KR-5600 next model up.

I would look for a fuse inside. I will have a look through my 5600 service manual.

Unfortunately I didn't have a service manual since there as none on hifi Engine.

I read on another site that there is a hidden 3 amp fuse located under the amp on the 4600. It sounds as if you have to open the bottom panel from that.

Have you had any luck with your Kenwood JR-4600 yet?

Here is what my Kenwood KR-5600 from the same lineup looks like as well as a photo of my KR-7400 from the series just prior to it circa 1974.

Not yet...just trying to get that "elephant of time" to work for me. While we're here, if it's a fuse, what is a common "blower" of fuses? I did talk to the previous owner who brought it back to the shop...he said it WAS a fuse that was out but didn't work with it enough to dig around. I appreciate you asking. I'll make sure to return a response when I know more.
Thanks tinker!
The customer and a few of us all agrerd it's too nice not to work.
By the way, tink, what's the watts on yours? They're beautiful!

It could have been something simple like a speaker wire shorting.

The Kr-5600 is 40 watts per side and the KR-7400 is 63 watts per side.

7400...the beast...lol...
Yeah, the 4600 is 35 a side, yes?
I'm kind of pinched for time today, I hope tonight "settles down"... I'm taking a guitar to my oldest son to fix the broken truss rod...

Yes better get that truss rod fixed. What make and model guitar is it?

The 7400 was the top model of that series but eventually they made a 9400 model.

It's a '76 Gibson Firebird I had since '84. The previous owner put big humbucking pickups in. I was looking for big humbuckers (was working with the single coil Telecaster for so long), just wanted a beefier sound.
While attempting to straighten the too dipped neck, I gingerly turned the nut on the rod (it worked on the Tele) and all of a sudden the wrench flops over on its side...with the nut in the socket...and the piece of the rod still in the threads of the nut! "Nut good"...
So all these years later my eldest starts a home biz guitar/accessory repair/refurbish enterprise. Tells me we don't have to remove the fret board. He has tools to carve a hole deeper around the rod on top and re-attach the (a new) nut.

That looks like a beautiful guitar. I hope he can get it fixed up for you.

I've got a couple of acoustics:
- Gibson Songwriter Studio Deluxe
- Blueridge BR-182 12 fret

They, too, look like sweet guitars! (Yours...,)
Yeah I love the Firebird. I've often said I don't believe there's another body design that could ever out-do it.
It needs a new, tighter nut cut for it...the strings roll when they're bent
Didn't get to go yesterday...it'll still be my slide guitar for awhile! :roll:
Thanks for the interest, tinker! I do have an acoustic, a Dorado (cheap line distributed by Gretsch. Looks like a Martin, plays well.

This is my baby Kenwood KR-33 which is an early solid state from the late 1960s.

This one was completely restored and recapped before I got it. It sounds really nice and seems to have more power than its ratings suggest. Very solid build quality.

Sweet! My first receiver was a KR-3130. Worked great for about 6 years before needing work to restore the one side gone out. Then years later it needed it again...the guy who undid the work basically botched up the circuitry, saying he couldn't fix it. That's when I got my brother's Sansui 2000x. A step up, but I always wondered how the Kenny would have sounded with the Advent Legacies.

That was too bad about your previous Kenwood.

I've also got a Sansui 2000X! 8)

That's an excellent receiver and a real collectors item. Also a real looker too!
