    Need help connecting EQ to Amp | Marantz 1090 \ Marantz EQ20

    Hello, I'm trying to get clarity around the best way to connect this EQ to this amp, as I cannot get it to work. On the back of the 1090, there is AUX (that's where the DAC is connected) and I have a tape 1 and tape 2 monitor. Should you connect tape 1 out to the EQ's tape in, then the EQ's...

    Marantz 2238b power supply adjustment

    I am just finishing up restoring a Marantz 2238b and attempting to set the power supply voltage. I can only get it to 29 volts instead of the 35v stated in the manual. Bias and DC offset are spot on. Does anyone have suggestions? And it is a concern given that it is working and sounds fantastic?

    Marantz 2285B no sound

    Hello, I recently received a nice marantz 2285B. It is a beautiful and a beast machine, in very good condition. When I plugged it in I noticed a slight HUM coming from the power transformer but it worked perfectly, the relay turned on and the music came. The first thing I did was to recap all...

    Marantz 2226B no R channel

    Hi, I was hoping someone could help me who maybe had a similar issue. I recently moved and after setting up my beautiful Marantz 2226b, I discovered the R channel wasn't working. My grandfather in law came to visit who knows a little about electronics and helped me check some of the internal...

    Vintage Marantz pairing

    Just thought I would drop here what a wonderful pairing I have found... Marantz 2270 with Vandersteen 1c's and a Rhythmik L12 sub. the sub integrates seamlessly with speed and texture. I think this setup would be hard to beat at under 2k.

    My Marantz 2270 doesn't sound any better than my modern Denon AVR-X1700H. What am I missing?

    Hi all, hoping for some opinions. TL;DR: I can't tell much of a difference between my un-serviced Marantz 2270 and Denon AVR-X1700H in A/B tests. What am I missing? Background: Since this summer I've been happily listening to music on my relatively new Denon AVR-X1700H feeding Klipsch Heresy...

    Starting my first 2325 Restoration and Looking for Guidance

    I just acquired a decent 2325 on the big auction site with the wood case. I received it several days ago and my first reaction was I could not believe how heavy the thing was! Even after removing the heavy wood case it is still a beast to move around the bench. The seller said the unit worked...

    Marantz 1090 Power Amp Transistor Replacement

    Hello, all. I have a 1090 on the bench that had a failure in the power amp driver board. It appears Q718 shorted from the base to the emitter. The transistors in the path current flowed all seem to be effected, though Q718 is the only one with a dead short. I'm going to replace all the effected...

    Marantz 2275 P700 Component Selection Affecting Bias Setting

    I read a number of threads about bias issues with the P700 amp boards in the Marantz 2275 and in other Marantz units. A lot of great information freely shared by other members. I came away not completely clear on the best approach to restoring the P700 board and thought I would start another...

    Marantz 2275 P700 Diode Questions

    I am in the process of restoring a Marantz 2275 and I noticed that on the P700 amp boards there are two red/green "diodes" installed across J703 and J709 and J704 and J707. Two other 2275's I restored did not have these "diodes". I looked online at various pictures of the P700 and yes, some...

    Sonos Port with Marantz receiver

    Hi, I hope someone with knowledge of the Sonos Port might be able to provide an answer. I'm thinking of adding a Port to my system, in order to sync it up with some Sonos players in other parts of the house. I'm in a bit of a quandary how I would connect it.

    Marantz 6170 TT Feet Compatibility

    I’ve got a Marantz 6170 with one defective foot. Apparently the feet are unobtainium. Does anyone know of any other Marantz TT feet that are a fit? The TT1060 for instance? I know I could buy third party upgraded feet but frankly I don’t want to put $100 into this TT.

Now that it works there is another problem, no sound in the right channel. I...
