I have doubts regarding transformer power for Gainclone amp. I made a calculations based on

the datasheet for LM3875 page 20, but instead of assuming a output power and R load

assume the constant 2x19 AC voltage from transformer, and calculate a power required for

particular R load. This is what I get:

1. 30W / 8ohm -> 2x19V 105W

2. 40W / 6ohm -> 2x19V 140W

3. 60W / 4ohm -> 2x19V 210W

What if I use a 2x19V _140W_ transformer and connect 4ohm load? Will it broke a

transformer because the current will not be sufficient?

Regards.
