Your advice is about 3 years late.

Electronics tend to fail at either the very beginning or very end of their life. Leaving it on a lot when it is new will help burn it in, and will ensure that IF it decides to fail prematurely, it will do so during the warranty period.

I leave stuff on for days.

Google is your friend. No, it does not sound like a real Hammond, but its raw tone is not much worse than some clones out there.

James Jamerson schools them all.
