I have long assumed that when anyone used the term the QUAD ESL they were of course referring to the original electrostatic model Peter Walker introduced in 1957. All other QUAD modes are referred to by their model designation---63, 989, etc., even the reissue of the original (a while after that model had been discontinued), named the QUAD 57. |
