Up to now I have done the vocm modification, I put the Jkrichards board and external power supply. As you said, I noticed improvements at each step.
Can I also put the 50v 100uf capacitor in R8 without having changed the Sparkos regulators? Thank you
This capacitor is needed for Sparkos only
Ok, thanks so much!
I ask for information: which model of Sparkos regulator should I purchase? How many pieces ? Thank you !
SS1117-XX
there are three +5V and one +12V on the power supply board

Very nice . Thank you very much!

Hi guys!
I had to replace the voltage stabilizers like many of you due to the Lundahl experiment and extreme heating (now I have Sparkos and bigger coolers)âŚI also replaced the D1-4 diodes with VSSB410S. My question is about diodes D5-D8: donât they need to be replaced as well?
Thanks
Hi Denis, do you have a link for the bigger coolers (Heatsinks) that you used.

No need, D5-D8 donât matter - they are auxiliary

Dear All,
As this thread had gone cold a little, the new activity reminds me that I want to encourage everybody who has already performed VOCOM mod and APS mod plus separate LPS for analog output to additionally dare to perform the power supply mods (for digital) that Anton_ss kindly had shared with us above.
I have performed them all (Sparkos regulators, Schottky diodes, better ground, etc.) and after a couple of weeks enjoying them, I am absolutely thrilled with the sound improvement over the âclassicâ VOCOM and APS mods alone. Everybody with only decent soldering skills and some basic understanding of electronics can do them and I assure you that they are really rewarding!
I also want to take this opportunity to deeply thank Anton_ss for supporting me patiently during my technical implementation. You are a great guy! Super competent and a great support!
Thanks so much and I hope that more people will dare to do these modsâŚ
Best
Christian

Hi everyone,
I totally agree with this statement. I donât have APS but I noticed a lot of improvements after making the changes recommended by Anton. He was also very kind to me and he explained many things to me. Thank you . I advise everyone to follow his advice.
Good music

Antonâs suggestion to connect the unused 5V supply to the display board in lieu of sharing power with the main digital board is a great suggestion. Itâs an easy, free mod. What I hear in improvement is slightly better imaging. My DS has XS4400 transformers, separate internal 12V supply and VCOM mods. Windom is my favored firmware. I too find Sunlight on the brighter side.

Thanks, but it wasnât my suggestion. Some tweaks are flying under the radar because they circulate only in direct messages between forum members.
I got this idea from @terryakhan. My gratitude goes to Terry!
