[quote user="flejguta_beo"]test points F,G & H [/quote] Now that is strange as those are points with voltages well above 0V. Now let's clear some points. - What is the device you measure the voltages with? A digital voltmeter or a moving-coil instrument? (I assume a DVM from your fractional values...) - as the voltage values on the

Just had a look at the schematics - there is no way to stop speakers 2 from working That'll backup Mika's findings... So either someone has clipped off those speaker connector wires or the connectors itself are faulty. Maybe even the wires have fallen off... Don't know your skills but you might have a look inside... EDIT: found this on your

ok, let's hear about your progress...

And we can easily wait for Lee to give exact numbers as the hotel reservations have been made by him... Gunther

Isn't there something like this on your schematics? I hope it's ok to put it here - if not; moderators: just kill the pic... At least it's dated 1974 and as such it's older than 30 years - a time limit that's ok with old schematics IIRC. On the other hand, if you are more into repairing there are a lot of schematics here on-site

[quote user="flejguta_beo"]Does it match with your schema?[/quote] Yep. But I seem to have the channels mentioned wrongly. C461 is the RIGHT channel, C549 the LEFT. We're talking about the right channel being faulty, correct? This should be the right part of the PCB, looking from the front of the machine. [quote user="flejguta_beo"

But I'm pretty sure you mean those 2 black wires going to the temperature PTC which would be fine with your mentioned 0.8V on the working channel. Problem is that the power

[quote user="MP_berlin"]Ist eine Nachrüstung bei älteren BeoGrams z.B. 3300 möglich ?[/quote] Genau das hab ich bei meinem BG3300 gemacht - nun hängt er an einer Ouverture - perfekt. Hat mich Jahre des Wartens gekostet aber dann tauchte mal ein defekter in der Bucht auf. Hab sogar mal drüber nachgedacht das Teil als
