I really have no idea whether this would be it or not, but I had a similar sounding problem on my 86 420 SEL, whereby I would hear a whine as I accelerated and then hold.

It apparently came from interference of some kind from the alternator and the radio. I replaced the original becker with an aftermarket and it went away.
