1980 930 and 1974 911 6 pin CDI box the same

I own a 1980 930 and 1974 911 with 3.0 w/ webers.

I just had my 1980 930 Bosch CDI box rebuilt due to a really low whine, also installed new Bosch coil.

I recently purchased a 1974 with 3.0 w. webers. Car runs fine, but when I turn car on I get NO WHINE from CDI box at all.

With my new 930 box it is extremely loud.

I know for a fact both boxes are Bosch 6 pin boxes. I wanted to swap the boxes and see if I hear the whine in the 911 with the 930 box. Are these boxes the same?

Would my 911 CDI box be working if it wasnt whining?
