465
The Tektronix 465 is a portable 100 MHz dual-trace oscilloscope with dual time-bases. The 465 was very popular and Tek made them for quite a few years. It is all solid-state except for the CRT. The 465 uses tunnel diodes with Tek part number 152-0125-00, which are equivalent to TD3A.
The 465 uses 155-0032-00 chips (their -01 grade) as trigger amplifiers.
