A Pair of Beomaster 1900 Receivers for Restoration: Unit #2 Wrap Up

The second unit of the two Beomaster 1900 restoration projects is complete.

After letting the Beomaster 1900 play music through the night ...











...I was ready to reassemble the cabinet pieces.

I secured the Bass, Treble and Balance indicator masks back onto the slide controls
















Then I fit the touch control panel onto the cabinet frame.
This can be a little tricky since the touch panel button actuators have to fit onto the button sensor posts.

















Always check that all of the touch buttons are working before proceeding with the cabinet reassembly.

























After the touch button control panel comes the tone control and FM tuning panel.
I applied some new Nyogel damping grease to the lid damper before securing the panel in place.





























There are two rubber stops for the control panel lid to rest against when the lid is closed.
Those rubber pieces are always deteriorated and falling apart (if not already gone).
I made a replacement bumper pad with my 3D printer that fits where the original rubber pads were.





























On the cabinet base plate I installed four new plastic cabinet feet that I ordered from Martin's Beoparts store.




























The final piece was the smoked plexiglas that fits over the touch panel indicator lamps. I had removed it to polish it. It just slides back into place.

Now the Beomaster 1900 is ready for testing in a listening room.
