Nice job on the IEC Simon.
Don't you espect these long earth wires near the torroid are apt for coupling?

Hi, thanks Jaap, the IEC was a pain but now I won't have a heavy power lead tugging on the board everytime I want to mod it. I don't expect the earth wires to pick up anything from the toroid, do you think they will? Won't any noise be sunk into the IEC earth?

Hi.

So I wasn't the only one with problems accessing the forum last night !

Cutting a hole for the mains connector is a pig. I was fortunate enough to find a square sheet metal punch [hole cutter] on a boot sale for 50p. It's not the correct size so I still have to file about 2mm from one side but it does save a lot of time and effort. It is possible to buy the correct size cutter for an IEC socket but the price makes it uneconomic for a one off [about £70]

If anyone is planning on cutting the hole for the socket, a round 3/4 inch cutter will save time and costs about £8

Andy

Hi Andy, I couldn't access it either. Bit late for me about the IEC, but Ad said he used a Dremmel and had it done in 5mins! Gees, it took me ages.

Morning Brent, yeh I was enjoying it yesterday, very nice improvement. But I took it back to the dining table last night to wire it to the IEC socket and also to add the two points I'd missed! Btw, the screwdown terminal is for the earth run that connects the mech pcb.

Those Kimber wires aren't overly flexible in bulk so it's gonna be a pain trying to properly mount the little board anywhere, but when I do (if I do lol) I'll try to keep the wires away from the toroid.

Thanks Brent finally a good place to put my silmic 220uF ;-)

You left C126 on servo untouched, any reason for that? Some mods say to raise that value.

Hey brent.

I was already trying that just before i saw your post

It's all good with the old -12V reg from the psu section

I guess il have to order another -12V audicom reg, do you think there is any point of me trying to get a replacement from them fro free, with this one being faulty ?

cheers

I would contact them yes

He is normally very reasonable.

Just tell them you soldered both regs into pcb to replace the original regs. And you had no audio and found the -12v rail to be 0v.

Dont tell them you were wiring them else where or they will have ammo.

Also have a close look at the reg pcb see if you can see a poorly soldered component, maybe its not lifting its current under load

bottom of his posts

Nad 1300 pre amp
2x NAD 2600 power amp's
Marantz cd67se
Philips 963SA
Kef Q35

some component and link numbers are different between cd63 and cd67

i looked at some mods posted and thought "that doesn't make sense"
then realised cd63 mod, me cd67

so everyone be carefull, check the model being modded

Hi all,

I've recently bought a used CD-63mkII and I've been kind of attracted by the nice performance you've achieved by modding it.

However, I dislike doing any of those mods before taking a closer look at the CD-player schematic and finding out what exactly I am doing. So I was wondering if some of you can post the schematic of this particular CD-player? It seems that all these models CD53-57-63-67 a very similar, so probably any other schematic wil do...

Regards,
Petar
