Here is a before and after shot of the heat sink with the output transistors. Sil-Pad insulators were used instead of silicon compound and 
mica.  
      
                  The back panel is worked 
over as described in prior 
write-ups. Everything is 
washed, RCA jacks are 
polished and the panel 
get a coat of wax. Special 
care is given to protect 
the paper labels. The 
paper labels can take a 
little water and mild soap, 
but you never want to 
"scrub" them. Blot gently 
and let air dry.
Shines up real nice...
