It's like saying all Panasonic caps take ages to run in, some may some may not.

If you have to bang your player to get it to read its the connectors.

Before you swap the laser I would hard wire between pcbs.

Hi guys,
I just finished to fit 4 BG (470uF/35V) in the op amp,....yes !! I got instant improvement in the all area, more weight,more warm and more detail.
On hand, I have 1 pr 11 R Allan Bradley and 1 pr 4R7 Tantalum, I will try to replace cheap metal film in the output, what the best?

Regards
aquar

Get a dog and take long walks. OR get a printer, a lot of black ink cartridges and print out 600 pages. When you've finished reading them, call the dog and take a really long walk.

Firstly look at the output section and its power supply.

Change C801 C802 for a larger value cap (Pana FC 25V 4700uF is not bad). Then change the 4 caps between the op amps (Black Gate is best here). Listen for a week.....

The you can change opamps to something better + bypass dc blocking caps and HDAM.

Hi Brent! The new laser (thanks a lot) seems to have solved the problem. That's a relief! I just love the 4562's. What a change! In spite of your reassurance, I MUST have compromised the 627's by running them backwards (silly blighter) because there's no other explanation for the difference I'm hearing. In my machine the 627's just don't work. But the 4562's bring the music back, the Marantz comes totally alive. It's suddenly a new machine, more like a musical instrument. Maybe what people here have said, that
the best op amp is no op amp, is true but until I have heard a better one, these are top-of-the-crop. I have them only running for 12 hours so I expect further changes. They have an astonishing level of texture. Honestly I can hear no down-side (nor do I want to!) In your opinion could a new laser have any affect on the sound quality? I can imagine that the amount of mistracking I was getting meant that the error correction was working too hard, but this is maybe totally unfounded.
Great service from that uk laser shop

With my almost complete lack of techincal knowledge on the subject I would say that a new laser may improve the sound over an old one (and all that "old" implies). Ray heard a difference when he swapped his too.

I'm pleased you like the op-amps. I think they're close to "no op-amps".

Simon
