If the 555 is operating as an oscillator, it could be normal.Is this normal or some kind of fault ?
By how much?The value of the PSU current display changes as the astable changes
We'd expect this when a power supply is operating in constant voltage mode.the voltage is stable at 9 volts
It changes between 0.014A and 0.022A, I believe this is 14 mA and 22 mA.By how much?

8mA doesn't seem unreasonable to me; a bipolar 555 can sink/source 200mA. What is the load on the timer? What is it driving? A schematic of the circuit involved would still be helpful.It changes between 0.014A and 0.022A, I believe this is 14 mA and 22 mA.
