The Tektronix 155-0080-00 (M125) is a Tek-made vertical output amplifier hybrid integrated circuit in a stud-mounted can.
It is used as the vertical output stage in 100 MHz-class 76xx scopes and contains three cascoded differential gain stages, two of which use the "ft doubler" circuit invented by Carl Battjes.
The 155-0080-00 consists of the main amplifier IC with 14 transistors, plus two D058 output transistors, all attached to the same ceramic substrate.
Used in
- 7603 / R7603 (U450)
- 7613 / R7613 (U450)
- 7623 (U450, in non-A version only − the 7623A uses a discrete vertical amplifier like the 7633's)
