SimpleSE Grounding Confusion
I have grounded my recent SimpleSE build according to wiring diagrams on the Tubelab site, but some researching on this forum has people saying to ground differently. I just want be sure I am doing this right.
I am using: an aluminum chassis, Triode mode, No CFB. I have drilleded a star ground lug near the IEC earth, with:
Each negative binding post wired to the lug
One audio input ground wired to the lug
IEC earth wired to the lug
OPTs screwed to chassis and so are grounded
Does this sound okay?
Also, I have an Allied PT coming. It has a gray shield wire. Do I wire this direct to earth or star ground or...
any suggestions appreciated, grounding always seems to be really complicated.

Put all grounds on one star ground, this includes power supply, output transformers, input rcas.
Earth ground the chassis
Inbetween the and the earth chassis lug, put this ground look isolator in:
Power Supply for Power Amplifiers
This puts the audio ground a few volts higher then earth so you dont get hum/noise.
So you got your star ground, connected to chassis ground, via 2 diodes (or 4 if you have a 20-35amp monolithic rectifier) a resistor, and a cap.
Here is another drawing:
zero volt line= audio star ground.
