Where / how did you connect the ground to the regs? Did you use the groundplane?

Hi Ray

Yes I had to use the groundplane!!!

I am how ever looking into a star earth senario where all my regs go to one spot. Just enjoying it at the mo.

Hi.

As your cd-p is so modded, it would be interesting to know whether altering the earthing arrangements would make a noticable audible difference. You are probably in the last 1% band !!!!

I agree. Its something I will be sorting soon. Making an earth point for my regs will be easy, but I will need to look further into the other ground points.

May have to have two ground points joined depending on layout.

I also want it to look good so ill not rush it.

Yes it is, not sure it made any difference but it never caused any ill effects either.

earthed to grd on iec plug?

the grd plane not earthed same point, then earth for ground plane
and all else goes to earth via (through) transformer then neutral plug.

is your neutral connected to earth at switch board (fuse box)?

if not earth at substation.

would be very interesting experiment.

I have IEC socked earthed to chassis and U201 @ the RCA output (like Ray)

Im not aware my neutral is earthed @ my fuse box, not looked.
Its probably done at the substation

Hi.

Keep the pound.... we need it to repair our cd-p's!!!!

That's one other mod I didn't mention.
My clamp is full of blutac, topped off with a 1921 old penny. Its about 1.5 inches diameter, copper (although even then it was probably an alloy of some sort) and rather heavy.
I thought it could be quite cool/quirky to have some 1920's technology in my CD player No valves though

Tried keeping the back panel fixed last night. It is much trickier. Will try filing down the lugs on the sides. I guess its not too important, if the cables to the phonos get damaged, I can easily rewire them and do it properly when everything else is done.

U201 is the earth point for the whole pcb, then to chassis earth.

put your meter across neutral and earth and see if you read anything
maybe mV's (warning only if tech)

i've seen 5vac
