[sdiy] finding a short in a Yamaha CS-50/CS-80

[Csaba Zvekan]

Ingo is right check the tantalum capacitors . They are all over the  
place. I remember having a short on one of the TBS boards. Check TBS1  
or TBS2 boards there are plenty of tantalum 0.33uF s there.
It's a good practice to replace all of them tantalums anyway today  
it's this guy here tomorrow on another board. If you know what I mean.
Is it a CS-50 or CS-80 ?
