    Squeezebox Schematic

    Hi,

    I'm just wondering if anyone has a copy of the squeezebox schematic? The seanadams.com link doesn't work anymore and i cant seem to find a copy anywhere else on the net.

    Thanks a lot,

    Sam

    Yeah, I have wondered how much crap I could attach to the side of my house before raising eyebrows at the PC...

    ( dac.pdf didn't get archived, as far as I could tell )

    thanks for the link, couldn't seem to find the schematic anywhere though...

    I was kind of hoping someone might have kept a copy. I'm about to try a few mods on my SB3, and figured the schematic would more than likely come in handy at some point. Oh well, looks like ill be figuring things out the hard way. I have the schem for the output stage of the SB2 as a backup.

    Thanks anyway,

    Sam

    The full schematics have never been released. However, I'm usually happy to answer specific questions.

    Like the new title Sean, sounds very impressive ;-)

    Strange that there was such a stink in the forums over the Logitech aquisition and this is the first change that I've actually noticed.

    Hi Sean,

    I'd like to fit a Newava S22083 1:1 in the SPDIF out circuit.
    Whats the output impedance of the chip used for the spdif, also is there a coupling cap on the output?

    Also noticed theres the KE grade dac chip already fitted in my SB3 which was a surprise is there a circuit diagram for the regulation we can look at? I currently run an external supply using one of ALW super regs with a LM1084 as the pre reg thats running the SB3, I was thinking of running the dac's 5v from the 5v input dc socket so bypassing the internal switcher and the internal 5v linear reg(if worth the time) also is the 3.3v reg for the dac run off the 5v reg for the dac or is it run from the switcher?
    Sorry for all the questions

    Kind Regards
    Leo

    Squeezebox no speaker audio

    Hello, I have a Squeezebox xr00001, no speaker audio. It does have audio out the headphone jack, and going through the menus I found a section which indicated "headphones detected" whether anything is plugged in or not. Any info on how it determines something is plugged in? I'd like to have a go at repairing this unit..

    Squeezebox v3 schematic question

    Hi Sean,

    Can you please tell me the component at Q2 in a Squezebox V3? Some type of transistor from On Semiconductor.

    My V3 is mostly dead. Just a faint glow from the TOSLink port. It may have been exposed to incorrect voltages and/or currents when I was troubleshooting a continuously scrolling display. I thought it was a power supply problem. Anyway, I tried some other power supplies I had lying around with various values I probably shouldn't have. Now it is dead except for the faint TOSLink glow.

    I found a thread in this forum with several test voltages that I was able to pass:

    • 5V in the circular via next to the large capacitors - not sure exactly where this one was located.
    • 3.3V on the metal tab of the voltage regulator U18 - PASS.
    • 1.2V on the C49 side of the inductor L4 - PASS.
    • 14.8V in the via next to the right side of the ceramic cap - PASS.
    • 56V anode supply for the VFD, right side of R51 - PASS.


    I'm looking at that transistor because it is close to the power jack, and because of possibly strange readings, though I barely know what I am doing.

    I have a Boom, Transporter, SqueezeBox V3, and Duet. Great products. Too bad Logitech didn't really do much with them.

    I don’t have access to any SB currently nor tools, I’m not at home. I assume there is a dc/dc boost converter to generate the 55v and that inductor may be part of it.
