searched the site and the web - can't find anything specific to the GA8027.
they seem to have been in the Yamaha PM700?

5 wires;
blue, black, green,
red, brown

thanks
 
Well, I only know the color code for a PM1000 output transformer and it's:

Brown: input +
Red: input grounded
Blue: output + (pin 2)
Green: output - (pin 3)

I don't think the black is connected, but my guess is that it's a shield. Check it with an ohmmeter and you'll find out.

Cheers,
