    Harman Kardon Citation I - To Mod or Not To Mod?

    Fate has blessed me with two Harmon Kardon Citation I tube preamps. One was beautifully built but also "well loved." The other was drastically modified over the years and is missing a lot of original parts. The "well loved" unit had a pretty messed up face plate, broken balance pot...

    The Backlight Buzz

    I have a JVC LCD TV of a certain age. It seems to have developed a buzz related to the backlight. I say "seems" because I recently got rid of a Dish receiver with a hard drive that made its own noise. It may have masked the TV noise. I know it's the backlight because JVC's remote has a...

When I first got it the tuner lights, 3/4 of the power lights, and the AUX light were out. After searching this site I managed to...

    Off topic...are LED lights safe for the eyes?

    I see them everywhere. Even some receivers utilize them. So are LED lights safe for the eyes? I see so many conflicting articles on the internet. But nothing definitive. It's almost as if if people are afraid to talk about it.

    Hello, I changed the relay and some transistors in the AU-5900, everything is working fine (sound is amazing), but since I unplugged and replugged the red led indicator, it doesn't always light up.

    New to the Marantz family

    Hi all - I just purchased my 1st Marantz piece this recapped 2240B from a seller on the SH site. It's plenty of power for my living room system and the FM, phono stage and aux input (with a little bluetooth receiver) all sound great. I've only had it a few days but I'm really enjoying the sound...

    HarmAn Kardon HK550 VXI LED Display is out. Can it be repaired?

    Picked up a HK 550 receiver of the Goodwill auction site and it works dandy but the LED is out. Granted I have a couple tuners I could use for FM but I'd really like to fix the display. I am handy as long as it doesn't require precise soldering. I know some techs who do computer stuff so if...

    Marantz 2240B Stereo Light

    So this past weekend I went ahead and replaced all the factory lamps on my Marantz 2240B receiver with LEDs. I purchased an entire LED kit specifically for my model. The Stereo light never worked on it to begin with, and after taking out the original bulb, it was indeed, dead. Soldered all the...

    First post here, so please be gentle. The stereo panel indicator lamp on my Pioneer SX-770 has died - actually, one of the leads broke at the base of the bulb and they cannot be replaced. No indication on the bulb of its specs, so does anyone know what I should replace it with? According to...

    Marantz 2238b Lamp kit

    I just picked up a 2238b and some of the lamps are out. At first I wanted to go LED to reduce the heat, but I want to keep the original look and color. Anyone know the best place to get the lamp kits, and how hard is it to DIY.

    Questions on SX-D5000

    I became the proud owner of an SX-D5000 this week. I was suprised at the size and weight of it but after giving it a clean and checking the DC offset I hooked it up and I was blown away. It's the best thing I've ever heard! Hooked it up to my PD-91 and starting playing some tracks through the...

    Yamaha CR-1020 LED Upgrade: Paradise by the Dashboard Lights

    Done, done, and done. Just finished reconnecting everything after pulling my CR-1020 out again, this time for a LED upgrade. The last of my lamps gave out the other day so I ended up ordering a set of 20 3mm, 12V pre-wired, pre-resistored, soft white LED bulbs from a seller on Amazon. They...
