The Tektronix M125 (P/N 155-0080-00) is a 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 "f_t 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. This hybrid is also known is H125.

Used in

7603, R7603, AN/USM-281C (U450)
7613, R7613 (U450)
7623 (U450, in non-A version only − the 7623A uses a discrete vertical amplifier like the 7633's)
