Atari Mega STe PSU Recapping Service
Atari Mega STe 1000 PSU recapping service – NOTE this is NOT a repair service.
- Removal of existing capacitors.
- Cleanup and preparation of area.
- Replace using quality capacitors.
- Test output voltages (not under load)
Recapping the Atari STe PSU is a good preventive measure, the reason being these capacitors are under alot of stress (which they are designed to take of course) however with age they start getting tired which could lead to issues later on.
All that needs to be sent is the Atari Mega STe PSU itself.
