Pioneer VSA-7015 - Delayed audio.

[Turnip]

Hi folks, got one where it powers up with relays clicking, but no sound at all for about five minutes, then perfect.

Note it has four relays which click in some sequence, but difficult to know which relays have clicked as all close together.

Tried listen but suspect I need a stethoscope, maybe the sort auto mechanics use to suss duff bearings.

Wonder if its a known issue  ? - Thanks, Chris.
