    Fender Acoustasonic 100 / 150 repair

    Got this Fender Acoustasonic 100 in for repair.
    Complaint: Supposedly does strange things, the instrument channel goes pop, crackle, no audio then all of the sudden works again?

    Well... Open this 15 year old sucker up and I am greeted with leaking capacitors. I changed these out, cleaned the board and no audio out of the instrument channel, but some weirdness is gone and sounds now clean on the second channel. So I put my laptop on there and cranked the music full tilt. Sure enough, it goes crackle and pop with the bass in rhythm. Put my signal geni on it and sure enough I got to way overdrive the input to get something out of the output and sounds like sh*t spread thick on toast.
    Parts quality isn't great, if I look at the caps. Its hard to work on as the board is a multi layer board and the traces disappear.

    Anyone got a schematic for a Fender Acoustasonic 100 or 150? It has a DSP also a USB etc... Have to admit, this is the newest Fender I had come in.

    Look at C181 and C184 located on the back of the amplifier. Crapola like that surely does NOT help. Seriously a solder brigde on C181???

      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...

      Help on car amplifier only one channel works
      by mikey5791
      Hi all forum members,
      Fyi, i have been working on this old model PCT-4082 (4 channel car amplifier). The owner said only one channel is working.
      My initial finding is this amp originally use Toshiba 2SA1943 and 2SC5200 transistor for its output but after opening the top casing i found it used Toshiba A1941 (pnp)and C5198(npn). I desoldered all the 4 pairs transistors and found 1 piece A1941 open(tested "OL" on all legs) and replaced the 1st pair with 2SA1943 and 2SC5200, thats why you can see in the picture it is the bigger size transistor. The other A1941 and C5198 all...

      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...
