Ticking noise in Audio Research Reference CD7


Hi,
I have a relatively new CD7 (probably with about 1,500 hours on it) and it recently started making this ticking noise each time I press "play" or move between tracks ("forward" or "backward"). While just playing the noise isn't there.

Any ideas where this noise could be coming from/caused by?

Thanks.

Hi, indeed I reached the second phase of the process and just before attacking the black plastic cover of the rails, decided to maybe discuss the matter with ARC first.
The issue for me is that, living in France, the local rep tends to charge tremendous amounts of money for service, may the sums be justified or, mostly usually, may they not.
Question: when lifting the square metallic cover, from underneath it's left side, a 1 inch long piece of a plastic tube (like the one used for shrink or the edge of the cables that run through the unit) fell into the palm of my hand. Is it possible that this piece serves for anything or is just that the person who built the unit didn't finish the cleanup properly?...
Thanks again.
Hi Elizabeth, I've opened the unit but can't see the rails. Do I have to also lift the CD tray to access those?
Is there anywhere where this process is described with pics for my layman self?
Also, I live in a very big city and there's a lot of dust/dirt/smog in the air at all times. How do you clean the guts of those units (CD 7, Ref 5, etc) that have practically no protection from all that dirt?
Thanks.
Thanks Elebroth. Will check that out.

Btw, taking advantage of the ARC experts on this thread and bringing back to life a sort of already discussed matter, does anyone here have an opinion about the power supply tube upgrade of the CD7? Is it worth the while namely sound wise?

Thanks.
Thanks guys.
Anyone knows of a reliable and reasonably priced source for the DR version tubes?
Cheers from Paris.
Thanks Oregonpapa.

Do ARC also sell out of manufacturing tubes such as the DR or the NOS 6550's?
I thought they were only selling tubes that are still available from existing manufacturers and their current tube types.

It would cost a lot to ship to the US and back and the local rep in France takes 450 euros for the upgrade (a hefty equivalent to 600 USD)...
Again , it's not a ton of money in the perespective of a good hifi system but yet it's not a given either.

Thanks for anymore comments if one has them.
Regards.
Hi Hansk46, just noticed your response here... sorry.
Thanks again and I'll immediately send you an email!
Cheers and good luck tonight in the Euro, we're crossing our fingers for your team.
Hello, now the player would also sometimes make this spinning noises on some CDs.
Any thoughts?

Also, I spoke to ARC about the power supply UG of the CD7 and they say this is needed essentially due to a design issue of the dual 6h30p tubes in the original CD7 design. Seems a bit awkward to me to have to pay and/or tweak yourself something like that in a unit that is so expensive instead of having ARC do it for free or a recall the original units.
Elberoth2, I can't find the Allen key that opens up the 4 little screws holding the plastic cover of the rails. Would you know what I should be looking for?
Thanks!
Thanks Hans for all your help with the CD7. Highly appreciated.

Now this spinning noise (other than the ticking noise that is as it has been before) is almost constant, unless someone here has a better idea, I'd have to take this unit for a repair, hopefully somewhere where I don't have to break my piggy to be able to afford it...
Must admit it's slightly disappointing to have such a high end component fall apart on you so quickly.

All have a good musical weekend.
bifwynne, thanks for your feedback...

I don't think that taking off the cover screws with a Philips screwdriver then doing the same with 4 screws of the plate and then to the 4 Torx screws of the transport plastic cover is calling for substantial engineering background. I have not fiddled with anything further nor I had in mind to do so.

And yes, I'm disappointed that such a unit after a few thousands of hours falls apart.

And yes, I'm also disappointed that I have to pay for the power supply upgrade which is a design failure of ARC, as explained to me personally by Calvin.

And yest, the costs of repair out of warranty in France, where I live, are outrageous and I think this is another failure of ARC to not be able to control the behavior of the people who represent them over seas. This isn't what I'd expect from a market leader towards its customers.

And the worst part of the failure, more even than the cost, is having to send the unit somewhere for repair which takes a long turn around time and in the meantime I just can't listen to music.

Bottom line, I love how the CD7 sounds but I think some aspects here, both commercial and technical, cold have been handled in a more customer friendly manner.

Sorry for being grumpy at your beloved manufacturer but this is what I'm feeling.

Enjoy the music.
Sorry, forgot the 6550 matter...

This idea came to me from people who have actually done it. I'm by no means an expert who would have come with such a thought from scratch.
Your posts on my other thread indeed put the doubt in my mind and I'm verifying if indeed this is possible to do.

Again, I had no intention of bypassing the instructions coming from the big leader.

Cheers.

PS
I'm married to an American lady hence know and respect all that is American workmanship, culture, etc (maybe excluding the food...).
No worries Bruce, I probably am also a bit tense as in-laws are vising here from Allentown, PA...

From what I know of the local ARC rep, the chances of him coming to fix my CD7 in the middle of the night or even in broad day light are smaller than the chances the supreme court will reverse its call on the Obamacare

I'll surely give Cal a call on Monday, as soon as the time difference between Paris and Plymouth permits; will make sure to pop your name in the conversation.

Regards.
Bruce, thanks for the Allentown connection idea but I think that sending the unit back and forth to the US would be very cumbersome. Only the thought of sending this big box with my in-laws back to the US makes me sweat, namely after what my mother in-law had to go through the time she brought over to Paris a King Cobra 3 wood I had ordered in the US... her experiences with security, customs, etc will be told forever around the family Christmas table while I feel bad and sorry...
Maybe we'll just keep your proximity in mind for a little audiophile encounter the next time we're visiting PA...

Elberoth2, indeed, it's taken sometime to take action. First of all there was only the ticking noise and speaking to ARC, Cal and the their service manager, they suggested to just leave it alone as they thought the issue wasn't serious ("it could happen that the transport ticks when looking for the next track"). Now the spinning noise is more serious (it's that one side of the disc the CD seats on is lower than the other and it touches the metal body of the transport when spinning) so since yesterday I just turned off the unit until it's fixed.
Looking for a transport in France brought zero result (believe it or not) and I have to move forward on ordering it from another EU country.

Can you remind me, from your knowledge, if the cd-pro2 is a straight on one-2-one replacement in the CD7 that doesn't call for any SW/HW modifications on the COTS unit?

Regards from a sunny Paris.
elberoth2, I guess replacing the cd-pro2 is a straight forward drop in that doesn't call for any specific ARC SW modifications or such, isn't it?
Thanks elberoth2.
BTW, I spoke to ARC and they claim they "modify the cd-pro2" but I don't really believe them and assume this is said for commercial reasons only.
I have to take my words regarding ARC back.

Actually, the cd-pro2 isn't a drop in replacement as the CD7 version needs a connector on position CL16 for the clock signal, this connector isn't part of the standard cd-pro2 transport sold by daisy or any of it's resellers.
Elberoth2, have you seen cd-pro2 units that come built in with the CL16 connector on the PCB?
would you know where I could get those?
thanks.
Thanks a lot Hans for your continuous support on this case. It's highly appreciated.
I dropped the player this morning at the techinican's for the PS upgrade and the PCB swap on the transport unit.
I'm crossing my fingers...
Regards.
hello Rugyboogie,

The transport was fixed. For future reference, the COTS transport isn't a plug and play in the ARC gear. The PCB plugs are modified by ARC.

The CD7 after the 5881 mod is better and even much (much) better when using a 6550 instead, IMHO, and the NOS the better.
I currently have a TS Grey Plates but when I heard what it's Black Plates sister did to my Ref5, I'm now awaiting another of those to arrive so I can plug it in the CD7.

Enjoy the music.
