Hi Lou;
No, but I have aligned many other receivers. Usually the alignment
instructions call for one of two ways to connect the VTVM. One is to the
AVC line where you peak a negative voltage. The other is across the
speaker where you peak a small AC voltage. Either method will work. All
you are looking for a voltage that is proportional to gain. Good luck.
