WOW, well this article just helped me locate my Fail 1 error on my just arrived 4808 quickly. Was looking through schematics while googling 4808 and here we are! Thanks Doktor Pyta.

Will still go through and check/change caps.

The noise level with the new fan is slightly lower but there is more important factor- due to worn out bearing old fan generated weird disturbing sounds, changed pitch etc.
At the moment the sound is definitely less annoying.

Was it You who bought 4808 which appeared on Ebay two weeks ago (or so) for $5000?

Yup Im the mad bastard that purchased it on ebay...

And its looking like more than simply a few caps. I replaced the 4 tants and the problem persisted, themisters appear to be ok, but I have noticed someone before me has been at the amp assembly and the heatsink assemblies, so I guess Im going to have to go over it in a bit more detail.
