I think there should be 4 rectifiers. Do the center legs of all 4 rectifiers go to the inductor to the right of the rectifiers?

Do all of the outer legs go to the transformers?

Use your meter to find continuity between the transformer and inductor.

Are there 3 small rectifiers and one large rectifier?

Are the three smaller rectifiers the same?

Is the board marked showing that all 3 small rectifiers are of the same polarity?

OK.

Did you check the rest of the outputs?

Does this amp use IRF640s and IRF9640s?

How many of each are on each side of the amp?

That doesn't seem quite right. There should be more 9640s but I wouldn't expect that many 9640s. Confirm that the solder pad for the third leg of ALL of the 9640s on each side are directly connected.
