    Advice Needed: Marantz 2385

    Hey everyone, I hope you’re all doing well. I’m a bit hesitant about getting this Marantz 2385 amplifier. I’m still a fan of Sansui and Pioneer, so I’m unsure. Has anyone here tried this monster receiver? How does it sound, and what’s the usual price range? I found one for $1,500 in mint...

    Marantz Model 9 Decent price? 2025?

    Hi all, I was wondering what you would consider a decent price on a set of model 9s. The most recent sales on eBay are all from a few years ago. I have the opportunity to buy a rebuilt to spec pair (rebuilt 3 years ago) for 12.5k. Is this too high? I feel like in the world of tube amps prices...

    Moving this question off another thread where I was able to get some great help tracking down an issue on a 1030 P700 amp board that was producing sound on the left side only. Once I was able to get sound out of both channels, I replaced problem preamp transistors and recapped the power supply...

    SP-1275 Information?

    Hi guys, I'm pretty new to the hobby but I've had a lot of fun finding deals and fixing up stuff. Recently I came across a seller clearing some speakers out. One of which were these Marantz SP-1275s. A quick search brought up practically nothing except an old OfferUp listing. They're in...

    Marantz 4140. Hard Clipping/Chirping at near max output, but only in 2x Channel bridge mode.

    I have had this wonderful old amplfiier for around 8 years. I got it completely factory, and somebody shorted out the lamp circuit. Easy fix luckily!! Worked great after clearing the short. The entire time I've owned the amp, it has had this strange behavior when I set it to 4x channel bridge...

    Marantz 2500 UBER HIGH negative dc voltage -14.90 VOLTS ! Help

    I’m working on a Restoration for a Marantz 2500 and I’m basically at the finish line just finalizing calibrations. It came to my surprise that both channels show a very odd -14.9 V, YES volts not millivolts when going to set dc voltage. The unit plays and sounds incredible, but this worries me...

    Marantz 6200 help

    Anyone familiar with a Marantz 6200 or similar that uses this kind of auto-return mechanism? My auto-in and auto-return are both pretty far off. I can get each function somewhat close following the steps in the service manual, but then it makes the other function even worse. The manual...

    ADS, differences in sensitivity.

    Is this normal? I own a set of L570/2 and a set of L780/2 bookshelf speakers, both sound great and the 570's are dramatically more sensitive than the 780's. Both sets sound fantastic to my ears, but I have to turn the volume knob up a little more to bring the loudness of the 780/2s up to where...

    Marantz C-CR603 repair

    Hello, Since my marantz M-CR603 will not power on, I've decided to repair it. From the main Switch Mode Power Supply board, no voltage is going out. Especially, a +6V is constantly supposed to go to the CPU for powering on by a push button. I've investigated the transformer responsible for...

    Marantz 2230B with NAD CD Player Doesn't Sound right

    Hey there, Recently bought a NAD C538 CD player and hooked up to my Marantz 2230B that I've been using for last 10 years. Tried the Aux and both Tape Inputs. All of them sounded fine until the bass kicked in and is distorted and blown out on majority of CDs (it's not a speaker issue either...

    Relay not switching on in Marantz SR 8010 DC - voltage problem.

    Hello, I have a problem with the relay. I replaced the power amplifiers and the famous STK3082 with the old NTC1339 (correct replacement). Well, I don't know if the diagram accurately reflects the receiver I have. I use the SR 8000 DC service manual. But I noticed that the voltage on the relay...

    Marantz 20B panel lights

    Good morning. I have a Marantz 20B with case. A few years ago, I attempted to ship it to a buyer via UPS. That was a mistake. They dropped it, bent the faceplate, but everything still functioned. I was so disgusted with them and me that I didn't deal with it until recently. I took it to a local...

    Marantz 1150 high bias

    I recently rebuilt an 1150 with a blown-up left amplifier module. Outputs were replaced with mj21193/4gs, bias transistor was replaced with an mje243, and the larger driver transistors were replaced with mje15032/33s. Everything seems to be working, except the bias will not go below 14 mV when...
