Re: Next owston meet ?

"would rather walk round town with a nail in my foot than go to Glastonbury" That is because you are a poof. Ali, perhaps Phil is a secret S&M fan, so Glastonbury would be OK, but a nail in the foot would be even better ? Or perhaps combine the nail treatment with a trip to Glastonbur...

Curious about the connection between mainscablesrus being a poof and Gwenda having a Glastonbury ticket? :lol:

Re: Computer Music Sans DAC

The Amanero have develop a new firmware on my specification to eliminate the bump at end of tracks with this DSD Pure configurations. http://www.audiodesignguide.com/PureDSD/index.html It's good that Amanero have made this update as it eliminates one of it's main shortcomings compared with the JLSo...

Re: Next owston meet ?

Tentative for me; would love to make it though so I'll try hard and, hopefully I'll be able to leave Judy on her own for the day (she's been unwell for a while).

Re: MJ Statistical Regulator PCBs

Looking good! 30mA is fine - well within the zeners' specs - no stress there at all... You are right in that until the heater is up to temperature and the tube starts conducting, all the current will flow through the zener string... I decided to use a front panel switch to manually delay applying B...

Re: MJ Statistical Regulator PCBs

Nick has said a minimum drop of 15V across the MJSR but to avoid too much more (he gives a range of 15-25V in the manual) - I'm dropping about 18V across mine (Vin 218V, Vout 200V give or take the odd millivolt). I'm using mine with a total load of 35mA, 20mA to the load and 15mA through the zeners....

Re: Nothing In Particular

Actually Sky broadband is pretty good down here, though I won't be using it for much longer; I too am in the process of terminating my Sky contracts, something I should have done long ago. I've cancelled Sky TV and bought a Freesat HD PVR (which actually gives better picture quality than my Sky HD b...

Re: Anyone with an i phone ?

They're pulling another wheeze too; until recently they used Torx screws to assemble their stuff but if you take a device to an Apple Store for repair they now swap all the torx screws out for a proprietary Apple screw design, regardless of what the repair actually involves. http://www.pcworld.com/a...

Re: Computer Music Sans DAC

Nick, the experience of others is showing that the Amanero board doesn't behave as well as the JLSounds in this context, nor does it have the isolation and reclocking of the JLSounds.

Have you had a look at HQPlayer?

Re: Computer Music Sans DAC

I've been making progress on this approach to digital playback - no conventional DAC chips involved. Just as a reminder, I'm using nothing more than an RC low pass filter to derive an analogue signal from a DSD data stream. Firstly, using HQPlayer I am now consistently upsampling my FLAC CD rips to ...

Re: MJ Statistical Regulator PCBs

So my MJ Statistical Regulator is now in service providing 20mA 200V of B+ to a Broskie BCF module.

The project is a 'no-dac' DSD decoder; I'll post some details in the computer audio section a bit later.

Re: Nothing In Particular

Regardless, a wonderful piece of drama and a fantastic world-class actor.

We saw him in the title role of Brand, another Ibsen piece, a few years ago - mesmerising.

Get yourself along Mr Bass.

Re: MJ Statistical Regulator PCBs

Thanks Nick, that's reassuring about the zener load at start-up. I left it hooked up and running for nearly 2hrs and nothing failed. the output voltage, measured with my old Fluke, is now a steady 199.7V (35 zeners). The zener current appears to drift by a few tenths of a mA but not sure how much of...
