  • Page 3: Unpacking Your Amplifier

    Congratulations on your purchase of the Convergent Audio JL7 A mplifier. Your decision is an indication that you are a dedicated Audiophile, seeking the state of the art in music reproduction. UNPACKING YOUR AMPLIFIER Open the box from the top. Remove the top piece of foam. You will now see a cardboard “cradle”.

  • Page 4: New Power Tubes

    NEW POWER TUBES circuit works best with tubes in the big middle section of the “bell shaped OptiBias™ curve” and so this is what we provide with your amps. This is also what we will provide for you when the time finally comes to replace them. Therefore, we recommend that new power tube sets only be bought from CAT.

  • Page 5: Power Conditioners

    POWER CONDITIONERS CAT amplifiers have built in isolation transformers which already provide tremendous power conditioning. Use of any additional external devices will restrict current delivery and degrade dynamics and bass response. SPECIAL POWER CORDS Your amplifier is provided with a decent standard power cord. Feel free to experiment, but beware of cords which sound significantly “different”.

  • Page 7: How To Replace The Lamp In The Power Switch

    HOW TO REPLACE THE LIGHT BULB IN YOUR POWER AMPLIFIER: Unplug your amp first! You must remove the red push button from the power switch. Grip the red button with your fingers on the top and bottom of the side which is out the most. Gently pull it out. It pops out easily.

    How To Repackage the CAT JL7 Power Amplifier: 1. Put the box on the ground. 2. Put the large piece of foam inside the bottom. 3. Put the amplifier in the cardboard cradle. Make sure the protective foam sheet is still in place, particularly in the front where it protects the shiny front plate.
