Counterpoint SA-5.1 --> is this normal?


Hey everyone, I recently acquired a Counterpoint SA-5.1, and it's lovely.  But this is a little weird, is it expected behavior for the unit?

The unit has a chassis with the dials, and a separate power supply.  The power supply is off, completely.  But the smaller tubes inside the main chassis are still glowing. 

In my world, off is off, so it strikes me as very odd they are glowing.

Is this behavior by design? 

It's not capacitors draining energy, since this has been happening for 3 days.

When I decouple the power supply completely, the tubes turn off.  If I couple it again, with the power button off, they glow again.

Thanks in advance for the help.
