Thank for the reply, I’m on a TPS 30 with a grounded power supply, haven’t encountered any noise issues so far, even with a Grid getting powered from the system.
I checked all the outs from the Ts-L, and it seems very noisy in the square sub out, the Sine is also quite noisy, its where I can hear the sine cycling and affecting the noise as it cycles. The fold out and pwm out is also somewhat noisy, its like the noise floor is very high.
Strangely, the triangle out is quiet.
