Gents,
I know its an old topic and I have read the 35 pgs in the meta but I'm finishing up a 6SN7 One Bottle schematic below omitting R1.
I'm having some hum issues after referencing heaters to ground with 2 100ohm resistors and was wondering if there is anything in my layout that could be affecting this. I have 2 6SN7wgta's and am rectifying with a 6X4 and each channel has it's own filtering after the 4.7k. I have a separate tap I could heat the 6X4 with if that would help. Can someone take a peek at my layout and let me know if there's something I can tweak to reduce hum? GRN is heaters, blue and gold in back B+, BLK =grnd, white are cathodes.
