Sorry, access problems are outside my sphere of influence.
The site is accessible from most points of the world. The problem is on the side of the cloudflare service. Today I will contact their support service.

Nevertheless, I see that over the past 24 hours on http://dsc2.ru there have been successful connections from Vietnam and Australia.

Ok.
Ipoci, and the last "the cherry on top" - you need to put R129 and R65 so that the total resistance together with the input resistance of the amplifier is about 5-7K.

My amplifier input resistance is ˜10K ... So, should I install ˜15K right?

yes

NXP

So has anyone been able to source old stock Phillips or NXP ICs for the DSC2?

All I can find is newer Nexperia stuff - any help is appreciated!

Pavel,


After building up a DSC 2.5 I’ve decided to have a go at the DSC2.


I have a spare Silent Switcher and am wondering what kind of input voltage I can send to the DAC side of the board. I’ve got the older, non-variable version so I’m stuck at 15v. Is this too much?

 

[ppy]

15V too much.
And I recommend using only linear power supplies.

Thanks for the feedback Pavel. I'll be stealing my LPS from the DSC2.5.2 for the final build - I was just planning on testing with the SilentSwitcher.



I'll find something in the 6-10v range for testing!



Thanks!

Hello everyone.
I am building this circuit but cannot find original Philips/NXP 74AHCT595 parts anywhere.

Does anyone have some to sell or know where to buy them at the moment?

If possible I would buy for 2 or 3 circuits (32/48 parts).

Thanks
Chris

Chris,

Shoot thuanth43 a PM - I just picked up a set from him.

I also ordered a set from DigiKey - they arrived with the old NXP logo and what appears to be a date code of 2016 - not sure if those fit in the ‘old’ or ‘new’ category.

I got 2018 code from both digikey and mouser, no old stock anymore.

While mouser have the 74vhct595 same spec as ahct, with no logo, should be the batch before formally transited to nxp pre 2017

Is anybody possible to provide an assembled PCB of the newest DSC 2 version? Im very interested!
Thank you, Norbert

Has anyone experimented with alternative output stages for Pavel' DSC2 boards?


I've been wondering about the Broskie BCF

Hello Pavel,
I am enjoying my DSC 2.6, and was thinking of building another, or another version like the one that holds a BB Black. Are there any kits still available? If so, what ones please.


I tried to PM, but your inbox was full.

 

[ppy]

No, there will be no more new kits.

Try to pm the user Thuanth43, he might have a board

Pavel,

I might be wrong, but the gerber file included in the page you refer seems to be in not ok condition, meaning that if you get uploaded the file to any pcb manufacturing house what you can see is a big working frame which includes the board inside. I don´t think the gerber is well generated. Would you mind please to take a look into it ? big thanks



cheers
Pepe
