The '''155-0059-00''' is a Tek-made HF Amplifier chip.
The '''155-0059-00''' is a Tek-made HF Amplifier chip.  The Tek custom chip
catalog calls it a "Gain Trim Amplifier".  It's a 12 lead TO-8 package.  Used in
the 7000 series 400 MHz and 500 MHz scopes in the vertical amplifier section.
The final vertical gain adjustment is after this amplifier and it typically
leads into either a [[155-0064-00]] or [[155-0065-00]] output amplifier which
drives the vertical deflection plates of the CRT.
 
Note that this IC can fail by becoming non-linear.  It will continue to amplify but
will show non-linear gain and clipping when using a step calibrator.
