    having a problem with my Marantz 2275 receiver..... DESCRIPTION - FM not in stereo: receives stations well enough, but they're playing in mono, and the stereo lamp does not light up - *however*, in a few tiny spots on the dial, I can sometimes get a shred of stereo, but extremely poor quality...

    Marantz 2275 Restoration Reproduction Lamp Housing

    I received a Marantz 2275 yesterday from a seller on USA Audio Mart. It is pretty banged up, slight bend in the lower rear chassis and the balance slider is snapped off which did not show up in the pictures. The right channel is out but both power amps work so I will troubleshoot the pre/tone...

    Subwoofer Connection

    I've got a Marantz 2275 that's connected to two sets of speakers -- one pair of towers in the living room and a bookshelf pair in the kitchen -- using both Main and Remote. I bought a SVS SB-1000 sub to add some low-end to the living room. It's a large room with 16' ceilings and the additional...

    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...

    Power Supply Caps

    Hoping to replace the 13,000 uf supply caps in my 2275 this past weekend but quickly realized I may not have enough heat in my soldering iron (60W) to deal with the jumper bar that spans the two caps. Anyone have suggestions on best way to remove/re-install the bar and wires? What iron would...

    2275 Preamp Gain

    Recently rebuilt a 2275 and unit is working and sounding great. Started on a 2250B and noticed that unit sounds louder in all modes (FM, AUX and Phono). I used the 2275 preamp into 2250 mains and the lower level sound was present. Reversed the wiring, 2250B preamp into 2275 mains and the 2275...

    Marantz 2275 - Right Channel P700 rebuild question

    Howdy folks and happy new year!! I’m working my way through my first 2275 rebuild (thanks for all the prior documentation!) and have come across a stumper. My amp has been working fine for a while and I’m stumped to fine the H704 transistor mis-wired. The traces seem to match the printed board...

    2275 replacement part

    How accurate is the cross reference chart? My 2275 needs the phones jack replaced. Old one cracked off behind the faceplate about 30 years ago. It looks like I can get the part from Canada but its listed as one from a 2220b. According to the cross reference chart it is the same YJ0100098 part...

    Marantz 2275 - Right P700 issue

    I picked up a 2275 from an antiques guy last spring for a good price. It'd never been restored but still powered up and sounded okay. I upgraded the lights and cleaned all the pots first thing and had a beautiful summer and fall blasting records. The right channel would drop out at really low...

    Long-time lurker, first-time poster here, I'm replacing a receiver for my tempest LS-5 floor speakers. My previous receiver was a Toshiba SA-7100 which was sold due to one of the channels continuously cutting out. My wife is all about the aesthetics of Marantz - she loves the blue lights...

    2275 - Cold Solder Joint

    Hey guys, I though I would pass on cold solder joint experience I just had on my 2275. I restored this 2275 about a year ago. Because of some distortion issues in the left amp, I essentially rebuild both amp boards by replacing nearly all caps and transistors. The restoration came out great...

    Upgrade from PM 7001 KI to 2275?

    I always loved the looks, and sound reviews of 2270, 2275, 2285 and 2325s. I heard (and loved very much) the 2285 in action, but only briefly and in a relatively unfamiliar setup (AR9 speakers) and an unfamiliar ambient (a rather big living room dedicated to hifi stereo), so I cannot really put...

    2275 Power Supply Troubleshooting

    I just now have also found a smoked R801 resistor on my 2275 PS board. The resistance measures over limit (OL) and it is burned. What related issue may have caused this resistor to burn? Is this R801 resistor intended to fail in order to protect other components? I was planning to replace it...

    Fighting with a 2275s FM MPX

    Hey guys, so I'm working on a 2275 and I noticed that I cannot get an FM stereo signal, I've checked using my FM transmitter I have that it is indeed the FM never switching to stereo, rather than it being the FM Stereo bulb driver being dead.

    2275 hum on unloaded Aux and Tape 1 inputs

    Is it normal to have a low volume hum when the input jacks for the selected source are unloaded? I know it is normal for Phono inputs. Set the Selector to Aux, and turn the volume waaay up. Low hum in both channels. Plug a CD player into the Aux input jacks and the hum is gone. Same result...

    Really?? What do you make of this? 2275

    :eek2: Picked up a 2275 this week. Initially, no lights worked on it. I could tell someone had been inside before because none of the side cover screws were factory. None of the boards looked they had been touched. I thought it was unusual that all light were out. So I started testing some...

    New 2275 Ebay Grab

    Hi all. Just picked up this 2275 from Ebay. It arrived yesterday. After shipping and taxes, I probably paid too much, but I am a big 2275 fan and was really itching for something to work on. I was a bit skeptical about having something like this shipped across county. The box was not...
