   A friend of mine just picked up this amplifier and I was wondering if   
   anyone knows anything about the company.  The circuitry consists of a   
   mix of mid 70s to mid 80s parts.  RC4136s (which were used by Tapco in   
   the mid 70s but were not used by many companies after that because of   
   their poor s/n ratio)  and a NE5532 which I didn't see in any   
   equipment before the mid 80s. The power supply has physically very   
   small Japanese filter capacitors and a toroidal power transformer,   
   again not common until the mid 80s.  Driver transistors are small RCA   
   metal can transistors of the 40409 40410 size minus the attached   
   heatsinks. (Mid 70s vintage)   My friend is also interested in the   
   year of manufacture.  Thanks.  Chuck
