What Is Inside A Berefsord TC-7510 MK6/3 DAC

[breakfastchef]

Seems that no one has ever posted pics of the internals of a Beresford DAC, so I opened mine today. This thread is as much about what is inside and how the unit may be modded to further improve performance.

The DAC IC - Aren't there better DAC chips that could go here? If so, this would be a huge soldering challenge for me.


Unknown IC(a) - ST EZ09716


IC3 - ST HCF4052/E9FB531


IC4 - CS8414-CSZ/GFBAAXFB0729


Op Amps - I believe these are 'not so good'. I think it may be relatively easy to put in sockets for op amp rolling.


Unknown IC(b) - TC4013BP/SIA 0706WC

Great pics breakfastchef. My picture taking skills are worse than my mod skills.
Have you though about trying the WM8716 instead? Better specs all round and goes up to 192KHz. I banged a 5532 in mine for the 4558, but I would advise you to use a surface mount IC. The yellow wires are additional mods I found useful if you use a WM8716..

Thanks Herandu. PM me the details as I have no clue what your yellow wires are for and what they connect to. It looks like you introduced another capacitor, as well.

cool, looks like they've stopped scratching off the markings from the ICs

The Unknown IC(a) is LM324
