I have the question in the main G9 help thread too but it is going a bit slow so I thought about trying a separate topic since it is in fact a general electronics issue.
So I am building a G9, schematic here: http://www.gyraf.dk/gy_pd/g9/g9_sch.gif
The 2 toroids (80VA Nuvotem encapsulated) work and measure fine when hooked to the mains power, but in the PSU configuration the 12 V makes a continuous buzzing sound. It is not from the electronics as same happens when nothing is hooked to the trafos except mains power.
I also tried each secondary besides the parallel, and same. Also from the other secondary of the 15V, all combos make the buzz.
Thanks
