    No analog output from SB Receiver

    My SB Receiver no longer sends output on the analog RCA jacks. The digital output is fine, so I can use it as a transport, but I've currently got it hooked up to a 2-channel stereo amp without a DAC that I can use. I assume it's just the analog section that's gone bad.

    I searched the forum and didn't find anything specific to the Receiver, but saw that there was a known problem with capacitor aging in the DAC section of the Squeezebox 3. Since this is my first post, I'll have to add the link to the thread in a comment. I found an internal photo of the Receiver, and it looks like the Receiver output section uses the same surface-mount caps as the SB3. (Link to follow in the first comment.)

    Does the cap aging break Receivers in addition to the classic squeezeboxes?

    Fortunately, I've learned SMD soldering in quarantine to build a DAC, so replacing a few caps should be well within my capabilities.

    This is the thread I read on the SB3 capacitor failures: https://forums.slimdevices.com/showt...l=1#post851581

    The SB3 are the same style (little silver surface-mount cans) as in the Receiver. Here's a review/modification suggestion article that includes pics of the Receiver analog output section: http://lampizator.eu/lampizator/Sque...queezebox.html

    I should add - the Receiver powers up fine, and appears to be stable when streaming, it's just that there's no audio output. I can easily control the Receiver from LMS or the remote, and I've verified that the RCA inputs on the amp work fine with another device. Network connectivity over Wi-Fi is completely solid, though I could easily move to an Ethernet cable for testing if needed.
