    Top tips for keeping a Naim CD2 transport going

    Hi Naim CD2 is struggling to play every cd. Tried new pucks but still get skipping tracks on occasion or discs just won't play. Occasionally if I hit the play button several times discs they will play eventually or skip to track 2. I fear the transport may be on its last legs. Anybody got any...

    naim AV2 tantalum re-cap advice

    Hi Did you make the changes ? Was there a benefit ? I took the lid off my AV2 some years ago thinking I'd replace the main caps and decided it wasn't worth it..... looked like a nightmare to take to pieces.

    Recapping Naim NAP 150

    Does anyone know what Naim would use as the modern equivalent parts when recapping a NAP 150 ? For example do they fit Kemet ALC80A103 or ALC10A103 for the 10000uf PSU caps ? What about the electrolytic caps ? I want to keep this stock design. Thanks.

    Dead TDA1541 crown in my Naim CD2

    I didn't mention I also put additional caps on the DAC regs across the existing 10uf adj filter, maybe got one wrong way round or cap failed. Removed these and crackling has gone away. I can only think the supply voltage changed, after heating up one of the voltages just wandered out of spec...

    Dead TDA1541 crown in my Naim CD2

    During some recent mods to my 3rd Naim CD2 when fitting a Flea to the +5V supply (maybe Flea has a fault as measured 5.2v) after switch on crackling can be heard from one channel after 10minutes of running. Bit of research suggests DAC has failed. (no problem with amp, wires etc etc). Has...

    Blown mono power amp - where to start on replacing components...

    Been away for some time from the forum but now I need your help ! Yesterday in my wisdom I tried to drive a piece of wire (not deliberately) with one of my (more NCC200 than Naim 135) mono power amp and in a flash and pop and big plume of smoke it was gone...... The 022R resistors are exploded...

    ALWSR Build Thread

    Hi All. I'm ditching 4 super regs and 2 more I re did the pcb. I'll post on the Classified section. All were working, although one had a dimmer LED, never got to the bottom of why. May be useful for parts or if anyone wants to use.

    A3 online prints

    Some time ago I did a little comparison of DS, Asda and a very well regarded pro printing service in Newcastle which cost several times more than DS. Asda was rubbish, DS outstanding and I couldn't tell the difference on two out of three prints in comparision to the expensive pro lab. I used...

    flea

    Tip for soldering SMDs is to use a pair of tweezers to hold the part in place, put some solder on the iron tip and tack one end of the part, solder the other end properly, go back to the previously tacked end and solder properly. A flux pen helps to.

    Any advantage for CAP6 in NAP 135 or 250?

    From my experience of cap 6 and my own cap 10 is that they significantly out perform the 22000uf used in Naim 250s, however I never tried one with Naim regulation boards in place. IMO the cap 6 is a superb addition to any power amplifier. Then move onto a cap 10 (5 x 4700uf + L) and improve...
