I was wondering if anybody knows where I can find a online maual for Kenwood
Amps. I tried their website, found a model that was close to mine, but it
doesn't have any technical data.

Thanks!
Mike
 
Hi,
the specs are not in the operators manual - you need to go to the glossy for
those. Dont have it electronic but the specs are:

40W RMS 8 Ohms
45W RMS 4 Ohms
THD 0.2% @ 40W 8 Ohm
THD 0.06% @ 1W 8 Ohm
IMD 0.2% @ 40W 8 Ohm
10Hz - 40kHz
damping factor : 50 @ 8Ohm
4 - 16 Ohm

anything else you need or want to know?

Cheers
Greg

Why thank you Greg : )
What I'm really looking for is: The two largest capistors, are they for the
power supply and if so, are they both the same IE 63v 68000uF or 42v
68000uF. My amp was serviced many years ago, and one cap was replaced, now
there is: one 63v 68000uF(new) cap and a 42v 68000uF (old). If they are for
the power supply seems kinda strange that the two would be of a different
value. Any thoughts?

** I bet they are 6,800 uF not 68,000.

63 volt caps are a standard rating - while 42 volts is rare as
anything.

Hi Mike,
Phil is correct 6,800 not 68,000 and the originals are 42V, no schematic -
opened mine up, the 1st time its ever been open too !!!

Yes, they are for the power supply, they are C29 & C30 down the back near
the bridge rectifier. I note there is no inrush limiting so don't use 68,000
or the fuses or rectifier will probably blow all the time.


You can use 63V units with no problem.
Use a similar 85 or 105 degree C rated cap.

If you find a schematic let me know too

Cheers
Greg

Oh I am so sorry, yes you are correct, it's 6800uF, not 68000uF, went a
little crasy with the zeros I guess LOL
Thank you so much for opening up your amp to find this info for me, much
appreciated : )
Makes sence now, those two caps that I mentioned, one 42v cap was replaced
with a 63v cap, because the 63v has no glue on the bottom of it and the 64v
cap,,,well I had to pry it off the board because it was glued. Good job
Greg, man many thanks again, you don't know what I've gone through to find
this info out. : )

I stand corrected and humble, my mistake it's 6800uF, not 68000uF, would
make a huge difference eh?
Thanks so much for your help!!!!!!!!!!!!

Hi Greg
Found someone that has a Kenwood repair manual. He is suppose to mail it to

addy. Might be a while before I recieve the manaual, I'll be in touch.
