Hi Scott, yes please..

Actually, it is a 8 pin dip. At this stage of the game, I would gladly 
take the LM305 even, and bend the legs to match the dip socket.. THe 
original part, LM376, the SK7643, and even the next, NTE1920, are all 
discontinued and everyone I have contacted so far, have none on hand..

It isn't just measuring the voltage and replacing it with something of 
equal voltage Andy, it is a controller type with feedback to match the 
users requirement of intensity.. :-(  Thanks though...
