    Marantz 2235B 2SC875 Substitution (H706)

    My substitution list states 2N3440 as the replacement but I bought 2 and they both burned up. In an AK thread I saw that the KSC2383 is a substitution. Does anyone know? I have those in stock.

    Marantz Model 2235B - humming after preamp restoration

    Hi all, I have a Marantz Model 2235B (first hand, from my father). It has been working forever, always been in a daily use. Lately I've noticed that the sound on the right speakers (Main and Remote) is lack of bass compared to the left side. I've decided to renew the required PCB and approached...

    Marantz 2235b - Tone Board Not Responding

    I recapped this unit and after doing so noticed that the tone board doesn't work anymore. The bass, mid and treble pots don't do anything. The audio signal is just passing right through and ignoring them. the loudness and Hi filter still work, but I can see in the manual that they aren't really...

    Marantz 2235b - Intermittent Dead Channel

    I've had my Marantz for about 6 months. When I got it, I put LEDs in, replaced the vellum paper and DeOxited all switches and knobs. Lately it has started to have an intermittent dead left channel. It is not a dirty switch. When I use the preamp outs to hookup another amp it doesn't happen (so...

    2235B and 1060 Capacitor / Refurb Questions

    I've got these two units and have a couple questions about recapping them. The 2235B works fine. I replaced the lights in it years ago, and other than adjusting bias and offset and a Deoxit treatment, nothing has been needed. This receiver sounds great, but I'd like to ensure longevity and to...

    2235B Rebuild

    Starting a thread for my rebuild effort. I bought this ~10 years ago but rarely use it. Has some hum and pop issues when shutting down. This will be my winter project - expect some questions from me! Here’s the first. Is this date code October 25, 1978? Or 1976?

    [Help] [2235b] right channel dies out intermittently

    I have 2 marantz 2235b systems that both do the same. The issue: the right channel on the main, backup/remote and headphones stops working after about 10 minutes (sometimes longer). If I turn the volume very high, the right speaker crackles and then starts working again. I have noticed...

    Marantz 2235B Pre-Main, Idle Current, and Other Questions

    Hi, I'd like to make this receiver 'safe' and relaible to use and bring its performance back to where it was when new. Cosmetically, it's probably a 9-9.5, and it's fairly attractive design anyway, so it seems worthy of the effort. I replaced all the bulbs about 10 years ago when I was using...

    Clipped output in 2235B at about 75 percent volume.

    I recently acquired this receiver which was dusty but otherwise functional. No appearance of any service performed. I cleaned the unit internally and Deoxed the pots and switches. Under power the unit has a minor 60 Hz hum on the phono inputs but the aux in is quiet. Those are the only two...

    2235B Tell me if it's worth it?

    Hello, I bought this cheap on ebay, in the pictures, all the buttons were in place, but after the lousy packing job, several are now broken. I have spent the last hour trying to fix the dial string that they tried to replace and strung incorrectly. My first question... in the first picture...

    Marantz 1070 + 2235B (pre/power) any good?

    Hi guys I have a 2235B marantz receiver and I might get a 1070 amp anytime soon, as it's a good deal, I've been thinking to hook them together as pre/amp, is that possible? any benefit in doing that? (anyway it's ok for me I can at least have them both operational). Thanks!

    2235B Bias Trim Pot

    Hi all, one of the bias current trimming resistors (R767) on the power amp board has gone bad and I am looking for a suitable replacement. The service manual says it is 200Ohms but I'm at a bit of a loss as to what I'm looking for:idea: Any pointers would be most welcome! Cheers guys

    Trying to decide on which Marantz...

    Long time listener, first time caller. I am looking for a Marantz amp/receiver to make a new setup with my dad's old Denon DP-60L. The turntable has been in storage since his passing years ago and I'm getting it back this week. I have a friend selling a Marantz 2235 B (for $300) and another...
