The remaining boards requiring some recapping restoration are the preamplifier board and the FM boards of the Beomaster 4400.
Again, the previous post here, show the before state of the boards.
On the preamplifier board I also replaced the six, single-turn trimmers for the Phono, Tape 1 and Tape 2 source inputs.

Now for the big step of reinstalling the boards and setting up the first power on test of this Beomaster.
