Kenwood KR-9600

I have been buying legendary vintage audio for the last 9 month's,  I came across this kenwood kr-9600, I named it Dino,  big, powerful,  and old,  To my astonishment,  it is in mint condition,  everything works except the power switch is stuck on,  to say the least,  I do not believe I've ever seen a tuner this good,  with a piece of two inche wire antenna this this picks up endless stations from abroad,  also,  this Dino is a whopping 160 watts RMS per channel,  I've studied everything about this unit,  I know exactly what I want to do to it,  from Etna simic two, nichicon kz and fg capacitors to modification's, my plan is to recap all 91 capacitor's,  put a relay with fuse on the power switch after it has the carbon cleaned out from in rush current,  change the op amp out on the tuner Board for audiophile grade new one for better sound , change out three resistors to aluminum finned new one's on the power Board,  the original one's are underrated and get to hot from factory, etc..., I need to find someone that know's this kenwood kr-9600 inside and out, that has reworked one of these,  competent,  to do all this work,  please help,  thankyou audiogon community.

Hi dlcockrum, you are exactly right about the power switch, the switch on my kr-9600 is stuck on, however, if you look on the net, the switch’s are incredible, the guy showed pictures of him taking the switch out, taking it apart and completely cleaning the black carbon build up out, putting the switch back together, re-installing the switch, works like new, also, after that, on another website, a gentleman installed a relay on the switch, with a fuse , the switch will never need repaired again, this off sets the current in rush to never happen, my darlington power pack’s are in pristine condition, however, even on another website, another gentleman that is an electronic engineer, shows how to rebuild the power pack's ’s, I need a qualified person to do all the modification’s and recap, I have just come across someone that might?, be of help, legendary amps.com a guy name skip, , do you know anything about this company?

My capacitor's are not leaking or  crowned,  I just want Elna,  and nichicon cap's through out,  with the crazy pick up endless stations tuner inside this unit,  I wanted to make this as high end in sound as possible,  I do know the capacitor's are orginal,  that said,  40 year's is amazing they work,  but Dave,  we both know I would get better sound with new capacitor's based on the age of the original capacitor's.

Don't know anything about Legendary Amps. Looks like they specialize in Yamaha. I would talk to several vendors before deciding.

The reason I brought up the Darlington modules is that extreme care should be taken during the refurb to protect these from electrical damage during testing/power up.

Sometimes the old adage "If it ain't broke don't fix it" plays out in these cases.
