Huh...quite a big heatsinks. This amp won't overheat.
Look at my LM1875 heatsink.

I didn't find anything like yours in my filing cabinet under "C" for Chassis.

it might be "big" but is it capable of dissipating sufficient heat?

...what may come handy in hot summer days.

Sorry...now I see you wrote a question.
Yes - that heatsink is more than enough for two LM1875. No need to worry. I would expect that big heatsinks in A class power amps.
I have noticed that you have both chips in one side. In worst case of overheating you can move one of those LM's to the other side and double the cooling that way.
