An externally hosted image should be here but it was not working when we last tested it.
My Audio Research D150 has torched the Power Line Voltage (on-off) Switch so it doesn't work anymore. My house hold supply is 230 VAC, so I figure that the best would be to hardwire the amp in the 240 Volts-mode. I don't mind switching the amp on/off with an external switch. My problem is that I'm not used to reading scematics (see image) so I'm rather confused. I can see the power comming in via the black, white and green wires, but which color wires should they be connected to?

Looking at the schematic at ARCDB - D-150
The transformer has 2 sets of windings, and a printing error at the switch description ( 2-120 should be 4-120)
As i see this you should connect :
incoming black to "upper " green
upper winding brown connectd to "lower" green , connecting the 2 windings in
series;
the "lower" brown connects ( it's already connected) to the fuze S1
The rest of connections to S3 should be isolated and clamped.
Do test with a variac or lamptest please!
