You're worried about something not worrysome at all!Gyro Gearloose wrote:You got it, the voltage on those big caps goes up. It doesn't matter what switcher you use.
From what I saw, when you reduce power consumption by virtue of replacing the linear regulator with a switcher, the voltage from the transformer does increase a little because the load lightens but mostly, the voltage simply does not ripple as intensely at each voltage cycle. It just says high a greater portion of the time.
You don't need to have capacitors rated for a higher voltage. In the 1541, the voltage at the leads of the large cap rated for 16V is 10.8V at it's peak - increase it by 20% and you get 13V which is still perfectly safe.
Same for the other big cap rated for 25V, same for the VIC-20...
No drama here...
