Hi All,
I am trying to repair a powered studio monitor. I have traced the problem to the toroid transformer. It keeps blowing fuses. The pcb is fine ( I have tested it using the transformer from the other speaker and all is good).
So what I am after is a replacement transformer. I have tested the voltage on the known good transformer and I get a reading on the two secondaries of 34v.
I have attached a copy of the schematic for the power supply section that I have obtained. Can anyone shed any light on exactly what transformwer i need. All the ones i can find appear to be very large that have 35v secondaries and looking at the schematic 35v would seem high anyway!!
I'm rapidly loosing my hair over this and really need this speaker back up and running.
Any help greatly appreciated.
Cheers
