    Sony HiFi Tuner loosing saved stations

    Hi All,

    I have a 20+ year old Sony ST-S320 tuner that 'forgets' saved staions from memory. When I opened the case I was hoping to find a battery that could be replaced - but none was present.

    I've attached the service manual. Can anyone point to where I should be looking to fix this problem?

    Many thanks.

      Many thanks for the help.
      I've ordered a replacement and will report back when installed.
