[ARC5] FS: SCR-543 WW II Radio Set

[1oldlens1]

Boiled linseed oil works wonders for wrinkles finish paint . After washing it  dry it and wipe down with the oil. Afrwe a few minutes wipe. Off the excess with a dry cloth and let it dry.  It will dry in a couple of hours but look wet, like fresh paint.  Lubricating oil never dries and will collect dust. Linseed oil will not and does feel oily.Sent from my Galaxy

    Thanks for writing, Dave.
      
      The key to the nice result was that the original
      paint and silk screen were actually intact with
      few "dings."  It was just very dirty.  I removed
      the meter, the speaker, the wooden "h",
      the DC vibrator supply, tubes, any other stuff
      a little water might hurt.  Turned my yard 
      water hose on low and gently washed it
      with a soft paint brush, then put it
      in the sun for a few days. 
      Gave all the controls and relays  a good shot
      of "De-Ox-It" and lubricated where needed. 
      
      When a black wrinkle radio has been this dirty,
      no amount of gentle scrubbing is going to get
      the micron-size dust out of the valleys and pores.
      it's going to look like a thin layer of "micro-dirt,"
      which is exactly what it is.  Attempting to remove
      this by force is going to damage your paint.
      
      I used another soft bristle paint brush,
      dribbled 3-N-1 oil on the dry paint and 
      "brushed it in"until it was evenly covered.
      I do this will all my black wrinkle sets 
      and even knobs like those on the TCS.
      Have been very happy with the results,
      as you can see.  I have sets I did this to
      10+ years ago and (with a dust cover),
      they still look nice.  The only thing  I
      repainted was the "h" logo. 
      
      The new "h" grill cloth is not original,
      but I like it.  Hand-cleaned the removed
      stuff and reassembled. 
      Checked all the grounds (some were bad).
      Replaced bad caps and "real bad" resistors.
      Gently burnished the relay contacts.
      and De-Ox-It on the power connectors
      and tube sockets.
       Powered it up with external supplies  and
      it past the "smoke test."
