    R2R DAC paired with vintage Marantz ...too warm, or a good match?

    Hoping some of you can share some insight before I make a purchase: I have a Marantz 2325 driving a pair of 4 ohm AR11 speakers, and currently have a sub $200 delta sigma DAC connected for streaming and CD. The turntable connects directly to the receiver. All three inputs sound great. But...

    Marantz 2325 P700 H706/707 Replacement

    I have a Marantz 2325 for which I am replacing H706 and H707. I have read some posts and seen some pictures of the need to cross two legs of the replacement transistors. I have accomplished this with H707 (replacement KSC3503) but as I look at the data sheet for the original H706 (2SA818) and...

    Why Does 2325 Amp Have Full Voltage Readings W/O PWR Supply?

    I am troubleshooting a possible short on one of the 2325 amps connected to a DBT and only having one amp in the receiver. I have the RCA connected to the amp only. Can someone explain why I can take full voltage readings with my multimeter on the components without the amp power ribbon...

    Marantz 2325 Transistor Substitutions.

    Hello Everyone, I need some help from all the Marantz guru’s. I have read in another post that the possible cause to an intermittent loud popping in the 2325 power amp might be the H706 - 2SA818 and H707 - 2SC1628 transistors. I see that the recommended replacement transistors are KSA1381for...

    Using an Amplifier, Marantz 2330

    Hello, I'm looking at getting a Marantz 2330 and there's a question that I have. With the speakers I just got I'm afraid that I need some power to really drive the speakers (100W+). My question is.... If I get an external amplifier for the 2330 and only use the preamp within the 2330, am I...

    Hey guys, so this will likely be my first big restoration so I figured I'd document it here and use some of your advice as well.

    Re: Marantz 2285B PJ01 Board ID
