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.

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.

Nice one! Did the extra weight make it spin quieter, read any discs better or sound better? Or anything negative?
Hmm, I can't work out why it's so hard to slot my back panel in when it's connected to the pcb, but I intend to attack those lugs.

I haven't seen a penny for over ***years
family came out when i was 5.
how much does it weight?
there are upgrades on the cd-pro2 with heavier platers

Undo the screws to the optical , coax and remote slightly. You wont have to file lugs off then.

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

Yes and no. When screwed in the rear panel is connected to pcb gnd via the rca , coax and remote connectors .
But I do have a wire running from this point to IEC earth

Good question. I thought it made good sense to do, so thought it was worth a punt. It definitely doesn't degrade anything. I used to have some problems accessing CDRs, I admit I'll have to try that again. I did the mod maybe a couple of months ago and have only really listened to originals.
I still have problems with the back panel, but its not a complete nightmare. It is tolerable (ish). Its definitely not as easy as removing it.
I'll see if I can get some photos at some point. Its an old penny, I don't know when they went out of circulation (I guess when decimalisation occured, bit before my time)
Off the top of my head (if I'd known this would of caused interest, I would have measured it) its about 30-35 mm diameter and must be a millimetre or so thick. It is heavy. I'll weigh one at some point. It is wider than a £2 coin (probably not much help for allan ther) and probably the same weight (it is thinner).
I have a tin of old coins and was thinking of a weight to use. I was thinking of an old foreign coin with a hole in the middle (lots of scandinavian and spanish coins are/were like that, amongst others) then I spotted a british coin that was older than the lot. Nostalgia took precedence in that decision. I think anything like a £2 coin would be similar.
Anyway, steered the thread through other hifi and now coin collection. I'm bad for off thread stuff. Sorry.
I need to show some photos at some point of the work done....

The £2 coin is the same size as the 1 euro coin
