the trabsformers are r core, there is one under the left channel and one under the right , no the star g is not connected to earth. should i try ampheads mod?
well, you're clearly getting noise from proximity to the transformers.
you should earth the amp chassis for safety reasons. what is it connected to, since you're doing star grounding? the chassis is connected to the source's shield? and if your amp faults with nothing plugged in, what happens?
you can try ampheads mod. i use dc heaters only, but i don't think this is relevant. worth a try any way.
