Hi Boeworld technicians ,

i have got a Beolab 7-2 which are dead. the 2,5 amp fuse ind the swich mode power supply keep blowing. The swich mode power supply have got module number 999  8053146  in the manual , it supplies the ice power modules with + / -  38 volts , and it delivers +/- 12 volts for the cros over filter network , and other voltages for the speaker.. does any bode have some experience with this , perhaps a dead ice power module drags down the voltage or the supply just lost its swiching power transistor. i have not ben able to find schematics for the speaker, the manual just contains block diagrams, they do not tel much about the supply cuircuit.does anybody have got the schematics or som experience with repairing the power supply ?? ,

answers would be much apriciated
