Hi all,

I moved onto the Stern preamp as I wasn't getting anything out of it and I came to use the scope and as soon as I connected the earth of the scope probe onto the metal work the thing burst into life albeit with the background hum still present. The hum is only noticeable at low levels and quiet passages and is independent of volume.

I'm a bit confused Chris by what you mean with the wire resistance for filter caps. I've been very careful not to pin the negative cap terminals to any point on the chassis it has all been wired by me to comply with the one earth point on the chassis.

You're correct Pete in how the 0v connections are. How would you recommend rewiring it?

Thanks for all your help guys.
