    Odd issue with my Marantz 2270

    I have this issue with the tuner in that the left channel isn't nearly as strong as the right, but the issue seems to be less severe if the balance control is set in the middle. With the balance set in the middle, I hear that the left channel is just a bit weaker than the right, but when I check...

    Marantz 2270 questions

    Hi, I've had my dad's 2270 for years, and in the past 2-3 years it's become unuseable. After 5-10 minutes of playing, I get intermittent and random crackle and static, and usually pretty loud despite whatever the volume is set on. I'm going to shake myself here, but mostly playing the audio...

    Marantz 2270 Crackle

    I have a hiss or crackle or static on both channels (but not at the same time) when using the marantz 2270. I switched the cables left and right channel and the static appeared on both channels. (not simultaneously) The amp was recapped and serviced just recently because of this but the...

    Zu Omen MkII... a good choice for me?

    I have a set of Klipsch RP 600m mkII speakers that I have in a bedroom office (run by a Marantz 2270 in another room) that I'm considering replacing. I find the sound a bit thin somehow for my taste (as compared with a set of B&W 601 in another room and my favorites, Jamo C103s). I have the...

    Aperion Audio 632-LR or Monitor Audio Bronze B2 vs Klipsch RP600 mkII?

    I have a pair of Klipsch RP600 mkII hooked up in an extra room. They are rather lively dynamic speakers, which I like and they by no means sound bad to my ears, but lately I've had an itch to sell these things and get something else which might have more heft in the middle. I feel like these...

    New Toy! ...and thoughts about DACs in general

    So, I just managed to leverage a few items (a few cables that I had but didn't need... given to me by a wealthy audiophile friend), which I couldn't seem to sell, into a trade for a DAC. I got a Chord Qutest, which from reading the reviews, is a pretty good score. I just got it all hooked up and...

    Gustard H10 with Sundara?

    I have a pair of HiFiman Sundara phones. They sound good, but I wonder if I could make them sound even better with the right headphone amp? I had a Schiit Vali amp that sounded good with a pair of Sennhieser HD600 phones that I had, but it sounded underwhelming powering the Sundaras, so I ended...

Those phones did indeed sound very good through that amp as I was getting a more open, transparent sound than with the...

    What is the gain of a Marantz 2270

    Does anyone know the gain of a 2270 with calculations? I can’t find it on the spec sheet. I try to calculate it based on the rated output at 8 ohm but I get Gain = 100. That can’t be right, right?

    Where to connect the sub on a Marantz 2270

    Hello, Is it right that you connect the sub on the remote speaker termials on a Maratnz 2270 and the stereo speakers on the main terminals? So when you are listening to music you should have both main and remote speakers switches turned on. Is this bad for the amplifier or is a 2270 made for...

    What is this capacitor for? I can't see it in the schematics

    It is connected between J761 and J758 on the amp board. Do you guys have any spec for this one and alternative replacement if needed? I think it says .01uF KCK

    My amp board wiring is not exactly like the schematics

    I have both amp boards out and was just checking the resistor values and I noticed something. If you look at the pics the resistor R785 (yellow arrow) is a short when it is suppose to be a 3.9ohm resistor. Is this normal or should i put a resistor with the right value? Why is it like this?

    Is it normal for resistors to have big deviation?

    I have a marantz 2270. I checked the resistor values on the amp board and some of values are at least 1k ohm off. Some are 200ohm off while some are exact. Is that normal???
