I'd replace with polymer capacitors, anything between 270uF and 680uF and 16v rating.
There's a high chance the capacitors are Panasonic, they used to prefer that miniature negative bar. it's 470uF but I'm not sure it's 35v rating, the voltage rating could be the K after 35. If it's actually 35v rated, the only reason I see for them to use such high rating would be to get bigger volume capacitor and as side effect lower esr. So if you go with polymer capacitors which have lower esr than any electrolytic capacitor, you would be fine.
