464
The Tektronix 464 is a portable 100MHz dual-trace CRT storage scope with dual time-bases. It is a lower cost version of the 466, with a slower writing speed and without the reduced scan feature. The 464 has a linear power supply. Triggering uses tunnel diodes. The vertical amplifier, U464, is the 155-0155-00. The 155-0077-01 is listed as an alternative part for U464.
