Dear fellow B&O enthusiasts,
I’m Stefan, from the Netherlands and new to the forum.
Since about three years I’m the owner of a wonderful beomaster 3500 that has developed a problem in the last few weeks.
I found out that the beomaster gets warm (about 27 degrees Celsius on the heatsink) when it is in standby. In a first attempt to tackle the problem I re-wired the transformer to 240 volts (as in the Netherlands 230v is the standard instead of 220v what it used to be when the beomaster was produced). This unfortunately didn’t solve the problem.
So, I opened the beomaster again and traced to heat problem to the TR18 voltage regulator (in the red circle) on module 3 (power supply and output amplifier).
My question is: what to do now, is it the voltage regulator going bad or could it be one of the other components on the PCB.
I hope there is someone here that can help me with this problem.
Best,
Stefan
