fuse problem - pioneer sa-7500

hey all, thanks for everyones help so far!! It is set to 240v which is the correct voltage for australia...the amp is in storage, i'll get it tomorrow or the next day to check to see if the internal fuses have also blown. The one i was referring to was on the rear panel.

Do i need any special equipment to check the BIAS and DC offset?? any pointers on how to do this??
