hi,

since when I was sick.

some testing or sad experience funished already.

1541/1541a need capacitors for coupling. For many testing result MKP was very good performance because of low loss.

I try another capacitors which was tin foil. 0.1uf(torlance within 1%) & test sound more clear & detail.

For all still waiting my DAC diyers. I will follow same nos of the TIN foil Capacitors for them to upgrade( free ). This Tin Foil capacitors( Made in France) was expensive but really good performance.

take a look for the photos & compare size of the tube. pls remember this was 100V capacitors only!



thx

thomas

Thomas,
First off, I am very happy that you are back home and on your way to recovering. I hope you have a quick recovery and are back to yourself soon.

I see that many people have received e-mails from you about their orders. I still haven't received a response to the many e-mails I have sent the past few months. Can you please check your inbox for the e-mails from me, and please respond as to the status of my parts.

Thanks for your time,
Donovan
