When I power this amp up it plays good audio no excessive current draw or heat . When I shut it down it takes about 5 min. For the led to go out. I assume after the caps discharge is this normal for this amp. I noticed some mods have been done (see photos). There is a resistor soldered to two pins of the That op amp on the bottom of the board also. Didn't get a pic while I had the board out.

It's normal for the LED between the caps to remain on for a while.
The mods are from MTX, I assume. I've seen similar mods on the 1000s.
The THAT IC is a VCA (voltage controlled amplifier).
