Yep - I had this issue with a CS80 a few years ago and eventually traced it to shorts in caps on the TSBs. Definitely should replace all the tantalums on both. The easy way is the kit offered on eBay if you don't want to figure out what kinds of caps to buy.

Thanks Tommy,Tsb 1 and 2 were partially rebuilt (there are some old tantalums on tsb2 left I think) with all the IC´s changed. I have never touched the TWS.Why do you think that might be the problem?The thing is that no fuse blows. The short simply kills my PSU directly.
