marantz

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...

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...

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...

Hello everyone, I found a Marantz 4300 Stereo and Quadradial Receiver. The owner told me it’s in good condition, and the price is €800. Before I make any commitment, do you think it’s a good piece to collect and worth giving a try? I know it’s a Quadradial Receiver, but is the price reasonable...

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...

Fresh off of finishing my first restoration, a Sansui 350a, I am going to attempt giving my Marantz 2215b a thorough going-through. I acquried this unit at a very nice vintage audio shop in Grand Rapids last fall. It appears to be in excellent shape and functions well, so my focus is going to...

Greetings, Someone gave me a Marantz SR-48mk2 receiver. A protection relay or something had begun cycling the power off and back on in shorter and shorter intervals until it finally stayed off. Idk whether it is the power protection or speakers protection. A respected local electronics repair...

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...

Hi I just bought a Marantz 5220 and Tadic in Serbia will make a wood case for me. I also have a Marantz 6300 that I plan to place on top of the 5220 when I get the wood case. My problem is which wood case for 5220 will be depth enough to have 6300 on top. Tadic tells me that the right wood case...

[Edit: It's the H802 transistor, but I can't edit the title of the thread] Hi, I am in the process of cleaning up and recapping a Marantz 2230 that has been in the family for over 50 years. I had a relamp kit I bought in 2020 still laying around, and decided to go all-in and do a full restore...

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...

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...

Calling all Marantz and FM "lovers" to try to decipher a familiar scenario that I have already seen on model 2230. 1) FM Signal strength meter barely moving (not even one line). 2) Center tuning meter (discriminator) centered and when tuning from station to station moving slightly left & right...

So in repairing a recently purchased Marantz 6110, I had to figure out a solution for the rubber feet as they wear out and deteriorate after decades of existence. In searching for a solution I read up on several suggestions but thought I could come up with something better. This is what I came...

Hello! I recently came into possession of some cool (I think anyway) audio equipment. It all belonged to my grandmother so I want to keep it and use it. I have a Marantz 6300 turntable Marantz 5220 cassette deck Arvin 75P88 complete cabinet with turntable and speakers circa 1965 I think...

Hello, Long time since I've posted here. I use a Marantz 2235b as a preamp going into a Carver M500-t power amp and it just sounds wonderful. However I decided I want a remote for volume, so I bought a Nad C162 preamplifier with a remote to use instead of the Marantz. Works ok but it just...

So I followed some of the other threads and here is where I am at. - With Volume down or at any volume, there is a slightly crackling on the right channel, this is with heaphones or with a speaker hooked up. - If I remove the pre out, main in jumpers I still get the crackling. - If I use an...

I'm doing an AM/FM alignment on a 2215B and I can find no information in the service manual or anywhere on the internet to indicate how the trimmers are oriented on the variable capacitor. As you can see here, the service manual refers to these 5 points for adjustment: And we can see on the...

Hi all, I recently inherited a Marantz 7C. After being assured it worked, I foolishly went to turn it on and the light on the front won’t turn on and doesn’t seem to work. Here are the internals/externals. Would anybody know of a place I can go in San Francisco (or the Bay Area generally) to...

As the title suggests I am looking to figure out he I can get some weird corrosion/residue spots removed from marantz equipment I just purchased. I read around a bit and it seems that you should use some sort of polisher, but I figured I'd ask just to be safe.

Hello AKers, I'm actually working on a friend's Marantz 1152dc which had a lot of corrosion caused 30 years ago by cat urine (just... imagine...) and then this amp stayed unused until now. I've made a lot of work on chassis, and fortunately inside the only board that had corrosion problems was...

HI everyone. Been some time since I've had to post here looking for some help, but I had a dear friend bequeath to me his Marantz 2325 and I've had a rebuild kit in my hands for the better part of the year sitting in a box. Now that the worst of the summer heat is over with, and my garage is...

Hi there! I had the project to recap my Marantz 3600 since a few years ago and today is the day! To make it easier, I ordered a recap kit on Ebay with all the necessary. Rubycon caps, Nichicon caps and films caps was in the package. The follow caps has been replaced with the same uF value but...

I won an auction for a Marantz 6200 a few days ago and picked it up today. I was hoping it would be clean and absent of too much damage but this is blowing my mind. This thing is in perfect condition. Even the shell looked flawless other than what looked like a recent scratch, probably from...
