    Marantz 2240B Left Channel cuts out

    Hello AK members: I am looking for help with my Marantz 2240B which I bought online a few months ago. It seemed to work fine for a while after getting it but I have now noticed this issue: The left channel cuts out after about 5 minutes of usage. If I let the amp rest (off) for a bit then...

    Marantz 2240B crackling/popping

    Hi All, First time posting here, but I've definitely perused the forums for awhile -- you guys are very legit! I have a Marantz 2240B receiver that I've had repaired a few times over the years and decided that when the two most recent problems came up I'd try my hand at repairing it myself...

    Right Speaker (STEREO) Goes Out After A Few Minutes

    I have a Marantz 2240B and it has been working great for a long time. I decided to replace all factory lamps with LEDs, this includes the tube lamps and indicator lights, including the Stereo light. After replacing them, everything was working great for about two months. Now as I am listening...

    New to the Marantz family

    Hi all - I just purchased my 1st Marantz piece this recapped 2240B from a seller on the SH site. It's plenty of power for my living room system and the FM, phono stage and aux input (with a little bluetooth receiver) all sound great. I've only had it a few days but I'm really enjoying the sound...

    Marantz 2240B Stereo Light

    So this past weekend I went ahead and replaced all the factory lamps on my Marantz 2240B receiver with LEDs. I purchased an entire LED kit specifically for my model. The Stereo light never worked on it to begin with, and after taking out the original bulb, it was indeed, dead. Soldered all the...

    2240B how to confirm if transformer has failed?

    I have a 2240B that just died. I'm reading 3.5VAC off the two yellow wires going to the power supply from the transformer. The two orange wires from the transformer to the rectifier are showing about 2.0VAC. Both show infinite resistance. The panel lamps light up. So the fuse and switch must be...
