  • Re: Beomaster 8000 tuner : nothing past 97 MHz

    [quote user="Dillen"] Maybe you have the answer in front of you. Martin [/quote] I'm not sure what you mean, Martin!

    [quote user="Dillen"] If the frequency readout is correct, I'm sure the prescaler is fine. Check the tuning voltage and the plugs/connectors related to it. Check also the interconnecting plugs/connectors between the two tuner boards. Regarding the prescaler, I recommend using an original TFK U264B component. The newer so-called "replacements"

    Hi Olly, Yes my PCB9 is the same as yours. So the mods aren't applicable here, it must be a revised, later board. (Edit: the SM says there are indeed two versions, our PC9 is the 8002493 ref., the older one (which needs the mods) is the 8002401 ref.) Since the can had already been removed (unsoldered) it came out easily. Contrary to what we see

    Geoff, It is different. For now the Beo is back together, but I will post a piccy when I have it apart again. Components are just not at the same place as yours, or as the service manual shows for that matter!

    Right then. On Tim Jarman's advice and after speaking to Richard (aka Richtoy) who had the exact same symptoms, I have ordered a new U264B. Are these kind of fragile? Should I use a holder? How the hell do you get this processor board out???

    Thanks Geoff, but my board is totally different. It is possibly a revised version. However, I fixed the presets (PX and volume), the memory chip has two folded pins underneath! Oh dear! Still nothing after 97 MHz.

    Good morning! Well nothing is missing anywhere. It is not very dusty and nothing leaks or smell! This receiver has a strange behaviour. When no aerial is plugged, it invariably displays 87.5 MHz at startup, whatever PX I choose. With some aerial, it starts at the old P settings (not mine). I can't store any new preselections, although the programming

    Yes, it shows correct frequency all the way to 97 MHz. Above too, with correct steps, up to 108 MHz, but I indeed only get static after 97 MHz (FM typical hiss). It sounds as if, past 97 MHz, it goes straight to 108, because I think I can hear very briefly all the stations between 97 and 108 before it goes into white noise only. A bit like when you

    Thanks. [quote user="Dillen"] Is it the same situation in both Aut. Tune and Man. Tune ?[/quote] Yes. Should I try to adjust 2R38 then? Or what?

  • Beomaster 8000 tuner : nothing past 102 MHZ!

    Hello everyone! I've just bought a Beomaster 8000. Everything seemed to work fine, although it was sold as partially defective. The amp section just works fine. I haven't checked any values yet but it doesn't get hot and sounds fine. I also thought the tuner was fine, tuned to 94.4 stereo, my favourite station, but then I realized that there's
