Contact John Kriner at Drake, 937-746-6990, apparently his personal business
will repair the R8 series, as well as the others.

Drake doesn't seem to want to do it..

The story behind the radio is that it was working perfectly until I turned
it on one day and there was no audio from the speaker. Audio is still good
from the aux out connection.

I bought a couple replacement audio output IC's, and replaced the original.
There is still no change.
