Type 1A7 | Type 1A7 (initially named [[F|Type F]]) was designed by [[John Addis]] and [[introduced in 1966]]. | ||
and | |||
== | ====Type 1A7A==== | ||
[[ | In 1968, the 1A7 was superseded by the FET-equipped '''Type 1A7A''' (designed by [[Thor Hallen]]), | ||
which also doubled common-mode rejection and bandwidth (to 1 MHz). | |||
The 1A7A's differential amplifier design was re-used with some modifications | |||
in the [[3A9]], [[3A10]], [[7A22]], [[5A22N]] and [[5030]]/[[5031]] scopes. The [[AM502]] and [[26A2]] use BJTs instead of JFETs for the offset current sources. | |||
Type 1A7A remained available until the end of the [[500-series scopes|500-series]] line. | |||
