Thanks so much. Very useful info on audio capacitors. It gets bewildering, i find. I may end up with my own cap collection, lol.

@Salas

Still I have some noise, posible as you said before due to mine bad design in the RIAA connections between components, mine question is:

Have I any way or general rules to connect the components or to ground to avoid the noise, as per your kind advice I use coax shielded cable for signal & I grounded the gnds of the input RCAs by a 10nF to the chassis also grounded to gnd chassis the negative output of the regulator.

Thks in advance

You mean some hum left? After you used the second psu it stayed the same or added some? Now you have two points from regs neg to chassis. If it was better before, try to have one common point for both to chassis. Also close the box if its open. Did you do the remote by now?

Yes, after 2nd psu stayed the same hum. About install one common point for both to chassis a do it before & the hum is more, better 2 points chassis for the neg. reg. Always the box is closed but without screws, no I don't have Rs.

So it is best with two points. Its a hands on thing to reduce. Sometimes a resistor like 10R can work between both or one point to chassis. Is something close to it that has Tx, mains cable near the inputs etc.

Yes, to one or both and listen. Experiments. Nobody can know the hum points beyond generalities if not there.

What AC cable? We were talking -reg to chassis. Is AC running near too?
