You've chosen to delete the fact that the P170, P270, A370, A470 and A570 amplifiers all utilised Hitachi lateral MOSFETs in their output stages. Why have you done this? My ownership of 4 or those 5 models, my possession of the service manuals for them, my repair and maintenance of approximately 30 of them for customers and my extensive discussions with both the designer of the circuit and Musical Fidelity's former Service manager all confirm that my statement is correct. On what factual basis have you made that change?

You have also deleted the statement of fact that the P180 amplifier was introduced in the early nineties. Again, on what basis have you deleted that statement of fact?
