Thanks Bob,

I have the excellent WD88VA Layout pdf 2006 (location drawing of the tag boards, components and wiring) but C15 and R27 are not shown on it.

My build sheets and amp are early with the 7 pdf’s dated 2006, 2007 and 2008 (VA and VAXL).

My Assembly Instructions pdf 2008 has a photo of the earth lift components fitted as Riggers describes and I’m glad he feels re-assured.

So,

Does anyone have an updated Circuit pdf which shows the 0V symbols (similar to the attached)?

Does anyone have an updated Layout pdf which shows the earth lift components?

I'll contact Matthew but he's away at the moment.

Ground symbols...

Hi all, Matthew has been in touch and reminded me of the new build manual he sent me dated 2011.

I compared it with the older pdf files and in the matters we are talking about (fitting the earth lift) they both agree. C9 neg and the black speaker posts are connected to the 0V star Signal ground point. The earth lift components are fitted between chassis Mains earth post and one black speaker post.

Matthew will look at updating the earth and 0V ground symbols for the next re-print. I’ve removed a line in my last post to avoid ambiguity. Any future builders in doubt please ask Matthew or on here
