Sony ta-e901 capacitors

[Chrisr3521]

Recapping this but come across some 470uf 120v caps at positions 513/514 in the power supply and 401/402 between amp modules. Any reason these need to be 120v or will 100v work just as well?

I hate to argue with Sony but.... the 120V cap is directly in parallel to a 5534 chip. If there is much more than 44V, the chip will die, long before the cap.

Maybe they had an excess of 120V caps.

The capacitors are in parallel with 27V Zener diodes, so 35V parts are adequate.
