[sdiy] Tantalums in Yamaha CS20M/CS40M

[Gil W.]

What was the reason they used tanatalums at all, back in the days ?
The writing on the circuit board, where the tantalum lay, shows the positive mark rather than the negative one as like any other polarized capacitor, meaning they planned dropping tantalums in there at the first place.... Any particular reason ?
