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

Still missing the balanced parts for my kit and selector. (I have single ended only). I already purchased the transformers so all I need now is the other channel, selector plate and the CPLD board. I will send a detailed email tomorrow, along with my new address.

Thanks,
Alan
