[BC] Gates early solid state consoles

[C. Park Seward]

Exactly right, Dave. I was referring to the line level signals.

You said in a previous email, "As I recall Gates/Harris changed the  
input transistor for a 2N1414 to a 2N1307." Was that a drop-in or did  
it require a new circuit board?

Thanks,

C. Park Seward
