Glenn,
Glad to here you are feeling better. I too have felt like I've had a cold for the past month. I assume it's probably from allergies this spring that I've never had before. Getting old really sucks and I'm not even old yet!:drool:
I have a KR11000GX and SUPER ELEVEN, probably no relation in build but has been a good read for me anyway. VERY interesting. Good luck on the project!:thmbsp:

Yeah...well...
Lots of demands on my time here...the boards have been completed for a while, but I got a whole house full of dead gear and more on the way.
I've been waiting for a 'quiet time' so I can spend the time necessary to shoehorn the boards into the receiver. Just seems like it never happens.

With AK getting bigger every day, I can see how spare time is something you don't have much of.
As a matter of standard operating procedure, I always pull the original Kenwood power ouput modules and replace them with my own circuit. I then sell the modules. That sounds greedy, but I pull them so that the original modules can be used by someone without the technical expertise needed to replace them with a non-standard part. That way, one more Kenwood is brought back from the dead.

It just snowballed into kind of a mess as I had some issues with the MOSFET modules, and then out of the blue I found a couple of original 9600 modules. I've got piles and piles of dead gear here, and as much as I wanted to complete the project, the time involved was killing me and keeping me from getting anything else done.One year later...
So yeah, I took the easy way out, but I would not mind finding another 9600 with blown outputs to try this with (once I could find some time to do so).
Don, I wish you'd start a thread, with pics, and show what you do to bring a 9600 back to life.
I guess I should. But first, I need to get some free time to work up the information in a form that everyone can understand.
Among other projects, I still owe the group plans for my electrostatic speakers I made from video tape.

That's a lost cause. Simply do the best you can, and provide a schematic.
With all due respect to the ingenuity involved in this project and the beauty of upgrading a KR-9600 in this way but if (when) my 9600 spits out a amp module I'll sell the good one and run the preamp-out into a 200 watt per channel (give or take) external power amp. The only challenge will be to get the power meters to work (if that's important enough to worry about).
I hope that day doesn't come and I try to be gentle with the volume. Just my 2 cents.

Believe me - that is the WAY hard way to do things! My way requires no changes in the already present Kenwood circuitry.
Here's a hint. The Kenwood module still exists - only it's manufactured in two pieces now instead of just one. I came across the modern version when I realized that the company (Sanken) that invested a lot of R &D in something like that probably would want to use it as long as possible. The solution costs about $16.00 to $20.00 depending on who it is purchased from.
HERE is a link to the data sheet.
Geez, I guess I'd better work up a schematic because there are a few little quirky things that need to be dealt with when using it in place of the original module.
No need to add a different heat sink, either.

I certainly wouldn't be averse to the 4048x. Any particular reason why you prefer it to the 4050? Edit: actually, the 4050II?
