Hi TiCatFan
Yes, our PSU has a lot more energy storage than the average guitar amp supply does.
I always keep bashing on the strings after power is turned off, as this actively drains the caps and you can hear the progress. It is especially important to do this if you are in the process of doing mods or repairs or incremental building. You don't want to be surprised by a charged cap.
Even though our supplies have bleeder resistors that will dissipate the cap charge over time, it will take a while for this to happen since the bleeder R value has to be a compromise between wasting power and heat, and discharging the caps in a "reasonable" time. The PSU has 440uF of filtering as a minimum - it actually works out to quite a bit more - and this is 4-8 times what is in many guitar amps.
So, always turn the power off and keep playing until the sound fades away.
