    Marantz Capacitor Identification?

    Yes I see that, I am asking what type of electrolytic cap they might be as opposed to the value and voltage of the cap. I have the service manual and it doesn’t specify the type just the value and voltage. Has anyone else seen the specific Marantz part number printed on caps before? It makes...

    Marantz Capacitor Identification?

    The cap in the picture is on the Dolby tape monitor board AW115-2003, cap number C566, there are over a dozen of these caps in various boards.

    Marantz Capacitor Identification?

    You can see the other side in the second picture, they are polarized electrolytic caps, but I am curious the type of cap they are. They have the Marantz part number on them from the service manual which is unusual. There are probably over a dozen of them in the preamp. I will add another post...

    Marantz Capacitor Identification?

    These silver caps have Marantz house numbers on them like some of their early transistors, I have not seen that before. Has anyone else seen these or know what type they might be? They are in a Marantz 3800 I am working on. Terry

    Distortion analyzer Recommendation

    I looked at the Quant Asylum website today and they do have limited availability on the QA401, but also mentioned that a new version QA402 should be released in March. I don’t understand enough of the difference in specs between the 2 to decide if I should wait or not. If any of you have...

    Distortion analyzer Recommendation

    I have repaired 20 to 25 different Marantz models in the last 5 years or so and I am curious about testing the quality of the repair, what Distoration analyzer do you guys use to test after repairs? I know I would need a low Distoration signal Generator as well. I am open to any recommended...

    Here are a couple more, the first one is the process of setting the bias points, there are 4 measurement locations that you have to balance. First each pair and then balance both pairs as close as possible to each other, and if that is not enough you have to keep dc offset to below 100mv...
