Ghost Sound LondonPower StandardPreamp

Hi Kevin,

Well thank you very much!

Yes, I built that one, with the kit you mentioned, with no local decoupling.
The alternate circuits work fine, but they are single channel.

Soem yeras ago I built a new version that has local decoupling but it does not make a difference.

I remember you saying "it's all I use" about shielded cable with not one but two conductors.
If I recall correctly Smile

Sometimes you can't get passed around that, but I used seperate cables.

I'll remove the clean channel completely, just to see what happens.

A while ago I tested with a separate tone stack box I built.
If I remember this right the problem went away then.
But only if I used the volume control that was in the box, when I used the vol on the amp the problem remained.

Strange I have this on both preamps.

What jfets do you recommend? I have trouble finding the right ones, in all my collected documents only obsolete ones are mentioned Smile
Or very expensive ones.
