SSLV1.1 builds & fairy tales
Ooops, it has a full own symmetric switching DC supply with virtual ground inside, just saw at Dyna's website. So it probably charges up at power on.

''The P-75 mkII power supply runs at over 1/4MHz. It takes the low grade single voltage DC supply from the ac adapter and converts it to the dual high voltages required for true professional quality audio reproduction. The operating frequency is over 12 times higher than the top of the audio band and it incorporates super low noise wideband regulators in its output stage to give ultra low noise supply rails. The internal P-75 mkII power supply is totally self contained and stores many times the maximum possible energy requirements ''

Don't touch anything inside, just feed it what it wants.

Also they ascertain: ''This means that the quality or size of the external ac adaptor is irrelevant. Increasing the capacity of the external supply will make no difference to the quality of the sound.''

Lets see, is it really irrelevant what quality you feed it?

My sister has been there off season once and told me that when the wind was strong and the sea was high it was an almost filmic sight when watching from the cliff perched houses.
Now the temps are summer time practically, everybody was out on T-Shirts in Athens today, should be splendid down south as well.
