Hello!
The number 1 main reason for the loud pop instead of the normal thump that the amp should make is due to the two big can type 4500 / 50 volt power supply rail filters needing to be replaced..
A secondary reason could be the many smaller electrolytic type caps on the other circuit boards that the amp has.

To nail down where the issue is coming from you can do this check out.

The blue wires from each front mounted PC board carry the audio signal to the amps rear wall mounted PC703 board.

If you cut open each blue wire one at a time and then power on the amp again to can then confirm if it's either of these two boards that are making the loud pop .

These wires can the easily be soldered back together and insulated.
