The SR808 Has 15 MOSFETS per voltage rail, so each channel has a total of 30 MOSFETs (15 X 2SJ50 & 15 X 2SK135). So the total amount for both channels is 60 MOSFET's. ClapClap

Well.....

Prognosis is not good. 

It's knackered...lol. 

If anyone knows of someone with a transformer from a non working 808, please send them in my direction.

How do you know the transformer is not working ?, has Kevin had a look at it ?

If Kevin has had a look at it, does he know the spec of the transformer ?

Yes Kevin has looked at it. He knows the voltages but not the wire guage.

I would estimate 1200VA from the physical size but I haven't taken it out as it's not a 5 minute job and I have more pressing stuff backing up.

Found this photo I took at Notting Hill Carnival in 2014.

In the right hand rack are six C-Audio SR-808. Must be the heaviest amp rack I have ever seen.

The sound system is listed as being provided by "CMC Matrix".

Maybe that is somebody on this forum. Possibly may still have spares.

You could of course send the transformer to us and we will rewind it for you. One offs are never at bargain basement prices unfortunately but we can soon dig into it and see what's what.
