Marantz CD63 & CD67 mods list

Hi all

Can anyone give advice on how to fit those tiny chip caps?
I'm looking to fit 10k0/0.1% at pos RD21-28, i'm not sure my hand is steady enough to just solder maybe a drop of superglue?

Cheers Ian

Use tweezers to solder one side, then keep the solder melt (use low power iron) and fit it in line with the tweezers. Here you can solder the other side now that it's hold from one side.

Superglue was excellent in this case

Ray I will be sending you a C2 to test soon. Could be ideal for testing on the 63 or would it be better to test on your main cdp so that you can test properly

That diy pcb looks good by the way

That's great! I'm looking forward to it. I have plenty of time beginning from next month, so I can do a good PFM Flea - C2 comparison. I will test it in my SA8400, because that's my best player. Make it a 3.3V 33.8688MHz then, if possible .

Thanks, I still know how to do it, even though it's been a while
Half the batch is already sold over the weekend...

The C2 outputs at 2.5V. The C2 requires approx 2 days to run in.

Thats great news about those pcbs

OK, cool. I will take enough time to let it settle. Just PM me if you need address details.

According to my freq counter your clock will run at 33.6867874Mhz

Brent

 

[6h5c]

is that a typo, or is it 5374 ppm off??

Ray

 

[Fidelity Audio]

lol it's way off. Yours will drift to 32.7Mhz

Help!!

I just made a big mistake

For some reason i had stored 100n x7r caps as the part no for 10k 0.1% resistors

I worked on the drivers, servo, Hf amp and controller had a short listen

In the same way as the last player i got over excited and ploughed on fitting what i thought was the 10ks at RD21-28

The player now wont read the disc... I dont want a 2nd dead player i have no test equipment any ideas very welcome...

Just switch the parts back to the orig components and it should be ok i would expect.

Do you have a Multimeter?

Lee.

 

[padman]

I dont know much about service mode but this what i have...

power up p 00
press fwd rwd i can hear the sled try to move makes a clicking sound

press skip p02
sound like something is spinning

press skip p03
the laser moves up/down rapidly

Hi Lee

I changed them back straight away before posting.
What level of multimeter would i need?

Ian

 

[Fidelity Audio]

Just a cheap one.

Make sure it does V ac/dc and also ohms (continuity)

Anything with a continuity test is pretty useful IMO.

 

[Fidelity Audio]

Yep thats fine

Brent

I didn't do anything!? Must be the panic...

 

[Fidelity Audio]

LMAO

Lets all blame Ray
