Thanks Junie,

Is there someone who has already tried without the 1uF cap ?
If you're a preamplifier used with this 1uF cap is the emotion of the sound completely gone.

Therefore, said Carlos first try without preamp and and use an passive volume control, he was quite right.

My passive volume control (41-step series attenuator from Acoustic Dimension) sounds better than my active Fettle preamp, with the 1uF cap. (
Can you still follow?)

BUT only without this 1uF cap my active Fettle preamp sounds better with the 41-step series attenuator from Acoustic Dimension.

Today I also listened music with an passive Inductive Volume Control from TRIBUTE and these one is the best from all "in my set".

And if you you use passive volume control, you take a very good 1uF cap because this cap sits in the signal path.

Regards,
Rudy

it is a good thing to use input caps just in case of a gear connected to the inputs carries some dc...try to use a better quality cap. I use a passive volume too and I have Sonicap 4.7uf that are doing a wonderful job. There are better and more expensive caps ,but that does not mean they will sound better.different caps...different sound. Good luck with your hunting!

Hi,

It's now likely that you have a board problem in the form of open or shorted tracks or an incorrect component fitted somewhere. Are you able to post a detailed picture of your board and its power wiring & grounding?

Is the lower end of R5 properly connected to ground?

Regards,
currentflow

you cannot easily convert a 100Vac transformer to run from 220Vac mains supply.

You can buy a 220Vac to 100Vac transformer that will feed the correct voltage to the 100Vac transformer.
Buy the correct transformer for your 220Vac mains supply.
