Musical Fidelty Tempest

Hi everyone,

Does anyone have service manual or schematic for Musical Fidelty Tempest?

This my own unit using for about a year bought used. Sound is clear a lot of mid lacking bit on Bass, I think this normal on this amp not sure.

But there is slight problem with the volume control i think.
When the volume is increased from low to mid it sounds powerful, When above mid to max not much of difference. It looks like it is not increasing gradually.
I have check the variable volume control is fine 100k not broken or open, NOT sure what the original K oms should be.
I think somebody must have repaired earlier replaced with wrong components.

I need the manual to get it right and calibrated.

Thanks alot,
Any info much appreciated,

Kind Regards,
