Yes, the scope will tell. But I agree that the idle current and power relay will have to be good first. Martin

Keith, Welcome to Beoworld ! Your Beogram 1000 has a one-phase AC motor, running directly from mains. Its speed depends on the mains frequency rather than voltage. Check that your Beogram's mains frequency matches the actual in your area (50 or 60Hz). The electronic board you are measuring on, are the preamplifier section. The motor acts as a transformer

I've wondered myself but yes, it is correct. Other amplifiers (I seem to remember the Penta's and also the BM8000) is given the same way. Having said that, to prevent crossover distortion, I like to set the idle current around 8mV across ONE emitter resistor. That's a little bit higher than what's stated in the manual but it provides

Hey, what's that ? - I don't believe it ! This finding alone confirms that the decision of restoring this set was right ! Martin

Underside view. Everything looks fine down here. No cracked solder joints, no burned PCB tracks, stray leads or similar. Very nice. Martin

What a beauty, no less than 11 valves will be working in here - hopefully. Having a closer look, I can already spot a couple of hours work now; - The dial string for the rotating AM ferrite antenna has snapped. One end of string is hanging down over the top metal chassis cross-bar, right by the two left-most blue capacitors on the vertical amplifier

Off with the rear and bottom covers and let's have a look inside. Looks fine with a nice layer of dust with no obvious signs of recent activity (no wonder since I've owned it for a fair amount of years and haven't been inside it before now). Undisturbed is usually good in that most things are presumably present and in their right places

Standard relay. Nothing fancy. 8 Amp if I remember correctly. Martin

Take the motor apart, clean and lubricate. It seems that almost every Beogram of this type will be in need by now. Other causes could be the main board speed setting trimmers and/or the fingerwheel operated ones onthe top panel. Excersize them a bit to shift eventual oxidation. ... "pushing the 33 speed selector makes the motor spinning, while

So far so good. Are you sure you measure correct ? (AC rms or pp) As I see it, the most important thing is to keep away from distortion. How is the sound ? Martin
