Hi I got an old mixing board called Studiomaster 16-4-2. Using google it seems to me that there are different ones called that and this is the one with five band EQ and LED meters.
I didnt get a wire for supplying power to it so i tried adding a standard power jack.
But then the fuses in my appartment blew.
On the outside of the cabinet is written:
"Fuse T2A (Inside voltage selector) 50/60 Hz ~ 100 120 220 240 V, 50VA Max"
But inside there is no fuse and no voltage selector. The wires from the voltage input goes to the power on/off switch and from there directly to the transformer coil. From the coil four wires goes to the phantom power switch and six to some circuit that then gives power to the rest of the board.
My first thought was that a previous owner could have added his own power supply, but then i noted that all the capacitors are by same brand (and looks like they are of same age) as the rest in the board.
I found a drawing of the power supplies of a Studiomaster 16-4-2 hereIt has a T2 fuse and says that you should the connect in series for 240 V power or in parallel for 120V.
Could it be that the board is connected for 110 V while im giving it 220? Which wires are to be connected in series if want to change which power it can use?
Any help or ideas is much appeciated
