    Sharp SC9570AV distortion, missing output channel

    15 year old, wasn't plugged in/used for 3-4 years.

    I have a recording of the working speaker, kind of cracking high distortion. Nothing out of the other one. These are using his 120w. I have some 10w PA speakers that both work on, so it's probably handling high loads

    I brought a 40W PA amp to his house and hooked his speakers to and both sound fine.

    Please tell me it's something as easy as bad caps lol

    Nice AB amp IC. Has it's own heatsink fan. Could be that. Probably not hard to find a replacement.

    Caps DO look good, but might be dried out

    CD player also does not work, I'm guessing rubber seat is dried up or belt has dusted/dried up

    Here is what I recorded. First is aux from cable box. Turned up high

    Next is fm radio, had to turn it down some, but still sound output is lower than normal. Also one left channel does not work

        old X58 triple channel board... memtest86 memory speed?
        by eccerr0r
        Anyone run memory speed tests with an old X58-based triple channel 1st gen or any other >2 channel board? The one I have is a Gigabyte I think.

        Anyway I had four 4GB DDR3-1333 modules in the 6 memory slots and got around 11GB/sec memory speeds assuming that it went dual channel since it didn't have enough modules for triple channel. Now I stuck in two more 4GB modules, but they are DDR3-1600. I'm still getting 11GB/sec speeds according to memtest86...

        Just wondering, anyone do memory speed analysis on these triple (and higher) channel memory boards? Are there any...

        Reverse engineering of 18650 4-channel tester
        by spleenharvester
        Hi friends

        I have reverse engineered this tester, schematic is attached and is complete except for capacitor values. These testers annoyingly have no model number but they are the ones you find on the first page of just about any website if you type in "18650 4-channel tester". There is also a 2-channel variant and a newer 8-channel variant. They are very cheap (about £15) and can measure voltage, current, internal resistance and capacity. They have a multicolour display for all these statistics. They also have terminal blocks so that if you want to use a breakout board...

        Marantz 1030: Extreme Bias Voltage and Distortion on Left Channel
        by TechGeek
        Hey all. I have this Marantz model 1030 amplifier with some problems.

        Problem 1: Left channel has extreme distortion under any kind of load. If you crank the bass control, it distorts to hell and gone.

        Problem 2: When attempting to set the bias voltage for the left channel, it's ENTIRELY too high. The service manual states 7.5mVDC at idle. It won't go below 130mV. The right channel has no distortion and I was able to successfully set it's bias current to 7.5mV.

        I think what's going on here is that something is pulling the bias voltage way up on the...

        American Audio VLP1500 Distorting on one channel
        by dicky96
        Hi guys I have a VLP1500 amplifier here - one channels works fine and the other channel distorts even at low volume settings

        Protection and Clip LED are off

        There is something wrong with the BIAS voltages around T16 and T18 (in particular) on the bad channel

        I tested all diodes and transistors in this area in circuit with diode mode - both channels seem identical. Same in resistance mode across all the resistors here.

        The output DC voltages on pin1 and pin8 of the 5532D dual op amp at the input of each amplifier module are the same, and the audio...

        Hitachi V19B01922 Channel Tune problem
        by dicky96
        Hi Guys
        I have a customer who has two Hitachi TVs in his bar, one is the model in the thread title and the other is a larger screen but has the same setup menu

        He also has an LG TV, so three screens in the bar

        I installed three Satlink ST-6503 DVB-T Modulators
        This model https://www.aliexpress.com/item/32916553905.html

        These connect to three satellite receivers via HDMI cables and then connect to a 4 way RF Amp that connects to the TVs on aerial cable. There is no incoming terrestrial antenna. I set the channel ID on the modulators to...
