I’ve had a BeoSystem 5500 for a few years now, and love it, but the BeoMaster 5500 has (and always has as long as I’ve had it) a few curiosities which make it less pleasurable to work with.
When you first switch on the BeoMaster 5500, it won’t reliably tune in to stations. My saved FM stations mostly pick up static, although sometimes pick up an entirely different station instead of the one stored at that preset, and entering the frequency number does the same thing.
Additionally, adjusting the volume can change the tuning. Sometimes (but not always) when I increase or decrease the volume, it will cause it to either go out of tune and pick up static, or it will go silent. This isn’t mute – the mute relays haven’t activated – it’s just silence. This can be “fixed” by going to a different saved preset and back again, or re-entering the channel frequency.
After the BeoMaster 5500 has been on for a while (about 25 mins), these problems mostly go away – going to saved presets works fine, and I can adjust the volume without worrying that it will interrupt what I’m listening to. Given that this seems to be a “warming up” type issue, my (limited) knowledge of 80s era electronics is telling me it could be a capacitor issue? Or perhaps some chip that needs to get warm to start functioning correctly?
Has anyone encountered issues like this before? Any debugging steps I can try, or solutions? I have reasonable soldering experience, and can work my way round a digital schematic – however analogue electronics like amplifiers and especially radio reception circuits get me confused!
Any help appreciated!
