The Tektronix 7A12 is a 120 MHz dual-trace vertical plug-in for 7000-series scopes.
Switches on the front panel control miniature relays in the signal path, such as those selecting input attenuators, through logic circuits. It uses the 155-0032-00 as a gain stage and the 155-0022-00 for channel switching.
The 7A12 was designed by Roy Hayes (who also designed the 3A3 before leaving for HP Loveland in Jan 1971). The Evaluation Engineer for the 7A12 was Peter Starič, co-author of the book "Wideband Amplifiers" with Erik Margan.
