On each channel change the 3 x 5k6 resistors adjacent to the polystyrene caps to 6k8.

Bump. Open to offers. Cable capacitances for phono cart loading consideration: S3 - 80pF Morgana - 150pF

Happy to provide support for these still, despite what happened to WH (nothing to do with me I may add 😬)

Yep, all Naim power supplies for audio except the very new ones were +24v. Tolerance was 23.7 to 25.5 V.

Good luck with it. The training is far harder than the actual event in my experience as you have to run huge distances in the weeks leading up to it. I haven't done London, I did Amsterdam. Let the crowd carry you, and don't do what I did which was think "It's just a parkrun" 5km from the end as...

I've just found some old documentation and the conversion involved a new main PCB and DIN plug replacement. But you can modify the PCB tracks as JJ suggests.

I've done it. Redesigned the Naim 729 board from the NAC72 and later into a universal filter board. Added an extra supply rail, built a carrier board for 4 of them and made myself a SNAXO 2-4 equivalent. Technically I can put two back to back and make an additional band pass filter for a 3 way XO.

That was us, we were the UK branch of a US company wholly owned by a Japanese giant. The business was very LA-centric due to its nature so we rarely, if ever, had to interact with Tokyo.

In my last role this was drilled into us time and time again. Except that most of the team I worked with were in Los Angeles and us being London based meant that we'd have 30 mins of overlapping office time each day to get all our meetings done in. As it had to be remote this was a lot easier at...

I did the whole WFH full time during 20/21. We were able to and we had the means to keep in touch and do our jobs as a team. Senior management even said 'you can't put steam back in the bottle' regarding working practices, implying they were here to stay. Then we were told to come in at least 3...

Still love the Duratool, but this video is worth a look if you're planning to buy one: https://hackaday.com/2024/04/07/comparing-desoldering-tools/

If the green high wattage resistors are smoking then you have serious issues. It's nothing that can't be fixed but it will need a technician and test bench.

In my experience the DAC chips fail far more often than the SAA7220. Just glue one on with superglue or a bit of epoxy. There are a couple of 5V regulators than run really hot but there's not much you can do about that.

For the record, the LED resistor in the 110, SNAPS, Hicap etc is a 3k3. Don't put it back under a rubber sleeve ;)
