NAIM CD3 June 20 2008 This player definitely deserves some serious attention. Where this machine excells constructionwise is the PCB layout, simplicity of digital section and cool mechanism. The grounding, the regulation, the capacitors - everything is from the best league, head and shoulders above the Philips / Marantz machines of that time. Product Manuals. Streaming & Multiroom Audio. Wireless System. Naim for Bentley Mu-so. Mu-so Product Manual. Power-Line Reference Manual - Multi Language. Hello to all can someone help me? The problems is the left channel audio has gone 'wooley' and muffled must checking the capacitors or truth solder?

NAIM CD3 NAIM CD3 Summer 20 2008 This participant definitely deserves some serious interest. Where this machine excells constructionwise can be the PCB layout, simplicity of electronic area and great system. The grounding, the regulations, the capacitors - everything is certainly from the best league, mind and shoulder blades above the Philips / Marantz machines of that time. This CD3 audio is quite powerful, rhytmical, organic sounding. I enjoy it both before and also more - after lampization.

Service Manual

Báck-lit naim logo. Very narcistic The natural PCB is shouting 'NAIM job!!!' I don't know any various other manufacturer so fanatical about star grounding, tantalum caps and control by LM317. I think that using tantalum caps will be a important element in development of NAIM home sound.

BUT - back to the delicacies: Verify out - 6 voltage government bodies and) each one - high finish Linear Systems LM317 - best of the greatest. Almost none of them of the caps are usually ultra advanced tantalum like in even more pricey modells. Opamps - oné of the greatest -OPA 604 from Burr-Brown. The caps around DAC - all kosher MKP's And the DAC is certainly a Beds1!!!

200 VA is less than in the big NAIM but nevertheless this participant has Greatly oversized transformer. Standard DIN plug from NAIM. Sorry - I get rid of them immediately. What a stupidity NOT delivering RCA's i9000 at minimum as an choice on the side. I drilled thé 10 mm holes for thé RCA sockéts. RCA't in location.

The above sketching displays my tried and tested suggestion for a snipit modification - hooking up the very first opamp to RCA't via a capacitor. Add to this a quick NOS mod and the participant plays MUCH better than share device.

The cost of this mód - snipit and N0S - is usually 10 Euros for a pair of good MKP caps (ór tantaIum in this case, connected plus to ópamp, minus tó RCA). And 2 Pounds for a pair of RCA'h. These are the active components - opamps and reIais - which we wiIl simply no longer use. This all turns into simply one triode.

The popular 6 government bodies with back again of the box serving as a radiator. I really dropped in like with this mechanism. The LAST system from Philips permanent magnetic CDM'h.

(The amount 9) The last possible upgrade would end up being the clock - there will be a regular one. We could repair here a superclock. I do carry out the NOS transformation. It actually allows this participant to enhance A Excellent DEAL! It should become obbligatory also without any other tweaking or lampization. Simply state: one - two - three and cut 3 monitors on the PCB.

As demonstrated below. Not much area for lampizator but there is certainly some. On the picture you can see the inside of of Compact disc3.

The TDA provides no overhead, but who loves you. The mechanism is certainly a FANTASTIC CDM9. It is certainly so basic and good that I suggest it really much. Guru at function! The little transformer and the pipe is usually from me.

With simply one Siémens ECC801S it sounds so significantly much better than the stock player that I can not really tell you. Lampization thrashés the NAIM 4-opamp per station analog stage. Actually if the op-amps are the best, and software is the greatest, it looses to the pipe in every imaginable department. Add to this the NOS lower and there you possess a dream player. Certainly in my top 5 worldwide. The yellowish wire are usually the NOS conversion and the track cuts are marked crimson. The nick SAA7220p/T can be bypassed.

In the red elypse the capacitórs which I wouId alter for better ones like OSCONS. l would but l do not. Simply a recommendation. The sound is therefore great from this Siémens ECC801S triode that my fingers were trembling. The schematics is usually this: Anode foIlower Ra - 15K Rk = 250 Ohms Ck bypass = 100 uF Tantalum (Yes ! this cathode résistor bypass is exceIlent) R conversion ánd grid - 82 Ohms Ia = 3,7 mA U= 150 V Ua = 90 V the transformer and anode power filter.

Somehow squeezed in this smooth box. Tube heater is certainly Air conditioning so it will not need any components at all.

Working full. My opinion: the audio is unusual: almost one of the best cdp i possess lissen. Problem was a faulty opamp (will be the firt period for me find a extremely easy and anomalous leakage). Sobstituted the opa604ap with opa627bp (even more dark audio and better treble, striper with tremendous difference in good).

The circuit is quite easy. The na-cd vs cd-650 half tuned, and cd150 fully tuned will be a little bit step upward, some armonics is definitely lost maybe.

Cd150 with nos convertion and fake SRPP AD825-6524 audio more armonics. The decision very tough now can be if the nos convertion is definitely better and if the opa alternative is the better way. Next week hard listening (nowadays 34°Chemical and 100% rh)!!!

Working full. My opinion: the audio is strange: nearly one of the greatest cdp i have got lissen.

Problem has been a faulty opamp (is certainly the firt period for me discover a extremely simple and anomalous loss). Sobstituted the opa604ag with opa627bg (more dark audio and better treble, striper with enormous difference in beneficial). The signal is extremely simple. The na-cd vs cd-650 half tuned, and cd150 fully tuned is a little bit step up, some armonics will be lost maybe. Cd150 with nos convertion and bogus SRPP Advertisement825-6524 sound even more armonics.

The decision very hard now is usually if the nos convertion will be better and if the opa alternative can be the better way. Tomorrow hard listening (nowadays 34°M and 100% rh)!!!
