I just want to say - I have recently repaired a couple of these and was shocked to see the batteries charge at a rate of near 300mA, for a good number of hours until a predetermined voltage is reached. The charge process is then pulsed every few seconds as if to determine cell voltage. I am not surprised that there are so many problems with replacement

So what we have here is that a 1k resistor between the output of the 74 to the input of the micro and this alone has made a difference... While everything is working, why not try bridging the resistor with a much lower value - measure the voltages again to assertain the current flowing and to ensure both sides are near enough hitting suppy and ground

Have you tried the trick Mika suggested?

:D

[quote user="hemenex"] [quote user="tournedos"]And another good way to permanently mute #1 outputs is to break a headphone plug in the socket... [/quote] Good point! Or probably leave one of those in it... [/quote] LOL I think if you managed to force one of these into the socket you would have more to worry about than speaker 1 not

The speakers work as active by the fact that the speaker output from the 8000 is attenuated then re-amplified by the penta amp! Not really ideal! The mod I did is simple enough - Prepare two lengths of wire with a DIN male on the end.. This will attach to the binding post of the speakers remove the penta amp, but watch the DIN plug and the wires that

60 pupils you're brave Jacques :) Lucky things is all I can say! You and family always welcome mate so give me a shout if ever close! Regards the MAR's there are some good youtube videos that are worth checking out!

Shouldn't get as warm on 240V Jacques so should be fine! One thing to add to Mika is when you hit the test button, the speaker to listen to is the left one as this contains the L-R signal. Great feature but you will never get a silent signal as both channels won't be that equal even with a perfect mono source! PSU transistors are on the right

Oh and the white Beo4, is that a shadow in the lower half or is it purposely shaded? If so it looks kind of good, almost a compliment of the lcd screen....

What a fantastic room you have there Leslie, I am quite envious! Beautifully displayed too!
