I`m stuck solid on this , ive solved the issue of the high input but I STILL have very low recording levels . the trimmers on the record cards dont do anything at all . can someone chime in with any suggestions as to where to look ?

play back is great , sounds amaizing , input is also very good , its only record that has the issue ,

Input the correct test signal to each channel in turn as per the manual and see what the signal is on the output pins of the measuring points socket, don't forget to pull the oscillator board for that test.
