Marantz CD63 & CD67 mods list

[SimontY]

Some interesting thoughts Ian.

Output transformers certainly do curtail the frequency response and hence need to additional filtering.

I think Audiocom leave the op-amps in because they want to maintain a strong output into any preamp/amp it may be connected to.

I'm not sure but I think just driving the tx from the DAC might not work 100% for every system.

They more likely fit them after the opamps for quickness. Straight onto the links. Call me a cynic but i've seen plenty of their/his work.

Brent

Yep

Also, I'm not 100% that the tx output is the best option. For sure it's incredible value for money, better than any opamp setup I've tried in my system, but whether it's better than a fully sorted DOS with proper regs & caps is another matter altogether.

Cheers, Lee.

I too am not convinced, there are holes in the audio. More messing around could get it right though.

Or buying some über transformers. Silver windings would be right up your street, and you could get it DCT treated

edit: I still think you should get the whole player done!

[Fidelity Audio]

I will get it done at some point. As soon as I think i've finished LOL

Got this from ebay last week, $6.47 + $7.10 shipping.

Here's the description:
This is an assortment of NEW CD Player repair parts.
Buy one, get them all. Take what you want, pass them along.
There are 26 small baggies containing diodes, micro push switches, earplug wires and more.
Most of these things look like items that customers ordered, but never picked up. Here is a list of part numbers from the larger boxes, pictured from the left, top to bottom:
Column 1:
Red Box: RCA 240166 Cover
Lot of Baggies full of small parts (diodes, switches)
Column 2:
JVC VCU1001-051 V Resistor Ref. #L0082

Marantz CD-63SEU/PU ASSY

The box the new marantz laser came in has an (old, yellow stained) PO label on it dated from 1997 (I think that was the date). I think the price marked was ~$95.00.

If anyone has use for any of the other lasers and/or parts, send me a PM.

Well let's say it: no more games on my CD-53, I've fried it!
Removed my +/-7.6V for drivers, even removed the wire to right Decoder supply, the same, no spin. And the tracks starts to look like dirt road instead of Monza!
Anwyway, I'll get the best CD43 of the world soon (CD-63 no way to match Brent's monster and about CD-53 no way for the ultra-super-regulated Ricardo's one). Changing the front PCB with IR remote will make it a sleeper =)
I think I should take extra care on factory parts removal on the CD-43, maybe cut legs of parts in order to let them fall by them self. Any advice to defeat these bended f... parts legs?
As for SMD caps from the CD-53...

A minute's silence please for Matthieu's player.

Brent - sorry for OT - as you mod them, do you have the schematic for the output stage of the Dacmagic (or 740C)?

thats not good Matthieu.

I have to say, i cooked 2 players along the way. It's all part of learning, broken tracks, smoke & pops!

You'll be surprised how much easier it is 2nd time round, you'll soon have the new one singing
