Kenwood KR9600 receiver


I have a problem with my Kenwood KR 9600 receiver. The volume “surges” or gets intermittently loud when I am playing music through the phono inputs.  It does not happen in tuner mode.  Is this a capacitor or power supply issue?  I hope someone might be able to steer me in the right direction before I start trial and error replacement of components.

Thank you to anyone who has advice!

I’m not trying to be funny.. OK.. Is there a TT plugged into the phono section? OR something else?

If it is a TT move it somewhere else, see if it still has the yo yo effect. (just might be a lot quieter)



In the off position and unplugged:

Flip/turn the switch a few dozen time.

THEN "tap" with a wooden pencil lightly.

Do that a few times... Clears the contacts, SOMETIMES..

Make sure there is no damage to the RCAs, in or out, clean and rough up the contact surfaces. At every point check, if something changes.

None of this stuff cost money ok...

If all else fails, on the bench it goes...and the cleaning and repair journey begins.. THEY bite.. be careful.. Discharge the caps.. AFTER you remove the cover, don’t mess around.. Now look first, then clean..
Might see a nest of  your favorite spider/Smurfs in there :-)
