In reply to angelo.

Nothing, except a slight variation in dc volts. Nothing significant. Manufactures would always try to cut cost by using the components that are just necessary for a safe operation. Only in well designed, precisely balanced circuits, such variation would make difference, as capacitor charge/discharge time, capacity, shape of wave form etc. are critically kept. However, in power supply, such changes do not cause any such major problems. This is what I have learnt!

No matter how big or small the device, you are a master in repair! And in keeping us in suspense too!
