Sorry, I don't know your name (Why don't people give their name when they post?)

Are you sure its the PA transistors that have failed?
Most often is the Driver board that fails. It runs too hot
The driver board is a real pain to get out and repair. You need 2 pairs of hands -- at lest!
There are some excellent videos on line that will help you -- just google 'Repair IC-7000 Driver board'

Again, make sure you have the necessary kit to undertake the repair -- and make sure you have some thermal paste to re-do the job the manufacturer should have done right in the first place!
