Fine business, snoop. If you want, you can put different value resistors in series with each of the diodes you added so that the amps power down in sequence as well. The highest value resistor determines which amp powers down last.
The left side of resistors R4, R6, and R7 could all be connected to the lab supply directly (instead of the emitter of Q1) so they don't drain off charge from the capacitors. That drainage affects the timing, but if you are happy with the timing as it is, it doesn't matter to leave as is. In any case, make sure the current and power dissipated in the resistor connected between Q1 emitter and ground is not excessive for Q1 or the resistor when all the amps are powered up.
Looking forward to the photo.
