Hi Dennis,

I was only (half) joking. But they're not being used so... I'll e-mail. Why do you want these not-that-good-sounding plugs?

Simon

I can buy 15,000uF 63V electrolytics for less than that.
I can buy 470uF 16V electrolytics for about 0.055 that's more than 72times cheaper.
I can buy higher quality electros ranging in price from 0.13 upto 0.28. That's still 14times cheaper.
I love the sound quality achieved from fitting BG caps. Ive tried many many caps and 'pound per sound' I believe they are the best.

I fit them in most things nowadays

Hi,

yes, that could well be the case and maybe the ONLY way to achieve that particular sound attribute. I cannot argue against that view.

But, that never makes them cheap. They are expensive, end of story.

Default Re: Re: cd 57 no sound and pops (help)

Thanks Glenn, Thanks Brent.
So, do you think the problem could be the DAC? :-(
In this player there aren't output El caps, there are only jumper.
Someone have a service manual of marantz cd57?

Thanks
R

Hi Riccardo,

There are a few things you can try to isolate the problem.

Do you (or a friend) have a separate DAC, MiniDisc deck, CD recorder or amp with digital input? If you get OK sound from the digital output then the problem is either the DAC chip or analogue stage.

I assume by "Bum!" you are referring to a pop sound when you press play or stop?!
This could indicate the muting circuit has failed.... do you get good sound from the headphone jack?
Can you measure any DC coming out of the RCA jacks? There are blocking capacitors preventing it coming from the op-amps, but the muting transistors are after these.

WARNING - test with some old earbuds that you hate as if there is DC or other rubbish coming out if the h/p socket you could fry your phones.

Then perhaps you need a "cheaper" hobby ... since this one if FAR from cheap!

If you are going to put inferior caps in, why bother upgrading at all? The CD63 already comes with Silmic and CeraFines ... about the only upgrade from there is Black Gates in the analog section anyhow.

If you DO want to do a budget upgrade on the CD63, leave the caps alone, bypass the output caps, remove the muting transistors, damp the chassis, get good feet, request some National LM4562 FREE samples and replace the op-amps, then bypass the HDAM. That is about as cheap as it'll get and be worth the time and effort to modify it.

Well well, I've followed Ray's list, wich uses no BG... I've as Ray's advice Elna RJH around the opamps. The whole PCB upgrade already ask for time & money. But I think I'm going to enjoy fully the next mods, Regs Coax & Clock.
Are the BG the only choice? Did I waste my money exchange the EOM Elna's for Ray's RJH?? (they was Slimic ou Cerafine? Maybe I can use them upgrading my old tuner or even the Arcam amp??).
Whatever my CDP sounds far better with the RJH

About test disc (if you fellows find this is not the place bother with disc I'll stop talking about, please tell me), I've enjoyed Leftism, and even more the fantastic and incredible Orbital LP "In Sides". It sounds new to me! If some of you got it, have an ear on... terrific!
