>>The other IC's are 2 OP-Amps (741 and MC4558), a strange  
 
14-pin voltage-regulator (7803) in the onboard power-supply  
 
and an ICL8038 <<  
 
 
 
In my unit, all of the part numbers have been scraped off the top of the IC chips, except for the metal can IC. It is marked 3263 7334LZ. There are two 8pin ICs and two 14 pin. The schematic matches my hand-drawn copy closely.
