Default sound stream

Hi all

I am working on a sound stream amp the cover is missing so i dont no the model.It look exactly like a spl fx1-5500d i had here last week.It has the exact same board.This amp came in with one rail cap with a split at the top.I replace it but am not getting good negative rail. +75.23v and -27.38v.I pull center leg on the - rectifier and i get 77.23v on it.Any help will be good.

Does the rail voltage become balanced if you place the black probe on the secondary center-tap (rectifier in the circuit)?

Post a photo of the board or a link to a photo of the identical board if you posted one in your other thread.
