This relates to an S9 but may be of use ref the feedback..

"Change C-38 on the echo board to 470uf 16v cap"

Info from Magnum,,,,

I have an S9 with the same power issue, just trying to resolve now..

Cheers Dave,..
Came in with 1 final blown in half.
Done replacements but still giving low output, still under investigation..
After 15 years never thought I would need all my repair equipment again !! Should never have sold it...
