Geoff Martin you IDOL .
nanan: mhhh what a shame :( Do you know someone that's capable of fixing these units ?
Yep.
I have fixed a few, most common fault is the surface mount ceramic capacitor blow and take the fuse out with them.
I take it you are talking about the snubber circuit, possibly the ones on the bridge rectifier. What values are you using? There is no component schematic that I know of.
I have the same problem with mine. Do you know what kins om capacitor they use?
Best,
CH
i have also two beolab 3 with broken power supply. In my case both fuses were blown an the same capacitor right between the primary mosfet and the transformer is gone. can anybody offer some advice ?
would be grateful if you could let us know what is the value of the sod capacitors around the mains bridge rectifier please.
Looking for schematics of beolab 3 for ages to get my faulty one going.
thanks for any help you can offer.
