Station Preset Memory Lost When Power Off

My receiver is a Kenwood KR-A46 but I couldn't find a forum for that model, so I'm using this one as the closest. For several years the station presets memory won't hold with power off. I didn't get a schematic when I purchased the unit so don't know how the memory is held. Is it a replacable battery, a capacitor, etc.. I didn't want to take the cover off until I had some idea of what to look for. Any help would be greatly appreciated.

    I've had my unit since it was new back in 1988 and it still is
    working great with the exception of holding the presets with power
    off. I did notice that it degraded over time where for a while, I
    could reset the presets and it would hold for several weeks, then kept
    getting shorter and shorter periods of being able to hold. So,
    that leads me to believe it's some kind of capacitor discharging
    involved and/or battery (ni-cad, etc.) discharging.

    A capacitor across the power switch is "usually" done to prevent
    60 Hz "hum" passing through to the output audio. Depending on how
    that cap is wired in, it would be difficult to supply power from that
    point just to the tunner memory and not the entire unit. If you
    change the cap and things return to normal, then you have found the
    problem and I will be forever grateful. BTW, Kenwood was
    "useless" in helping; just sent me to an "authorized" dealer to fix
    and/or "buy" a schematic. I hope your fix will work or maybe more
    people will write in. I hope to hear more.

    Hello,

    I have the same problem since few years ago.
    Then came added that the receiver after power off the last adjusted device (tape, video, tuner ...) no longer remembers.
    Is there perhaps already a solution to the problem?

    After few few days powered off, preset memory is lost memory ok if unit is used daily. Probably a capacitor, but without schematic, how do I know which one, and where do I get a replacement?

Have same unit, exactly the same problem: station presets lose setting when power is off. I've opened the unit; there is no apparent battery of any kind.

As long as the unit is powered up, the station pre-sets seem to hold. There IS a capacitor across the power switch. Some A/C will therefore be transmitted into the unit when plugged in, even with the switch off. If the capacitor is open, no charge will enter the unit when the power switch is open. I will probably replace this capacitor and see if that fixes things, but it may take several days to do so. Has anyone else tried this?

Kenwood Receiver (KR-A46) Loses Station Presets on Power-Off

it sounds like the button cell battery inside the receiver has gone bad if you take the cover off you will see it its about the size of a quarter. You can purchase a new one for around $4. Let me know if this works or if you need assistance in taking the cover off the receiver

Station memory problem

Sorry, I haven't addressed the station memory problem further since replacing the AC switch by-pass capacitor, which same didn't solve the problem. I'm using the receiver only as an amplifier for a Roku SoundBridge, so the station memory isn't a problem at present. When we return to AZ, I may look at it again.
