@Flavio:
Very beautiful A3000 you have!
For the two problems you have:
1- Battery: now exists NiMH batteries with the same shape and capacity of those old NiCd ones, go buy one and problem solved;
2- Toccata: Swap the electrolytic capacitors (SMD units) for new ones. Even regular-sized (105°C, preferably) will be OK.
