504

The Tektronix 504 is a monolithic oscilloscope with a bandwidth of 450kHz introduced in 1960. Triggering is done using a multivibrator made of a 6DJ8 tube. The vertical signal path has a 6DJ8 first stage, a BJT second stage, followed by the the output stage. The vertical and horizontal output stages uses pairs of 6CB6 tubes. The CRT circuit uses a single 5642 to generate the -3000V cathode voltage. There is no post-deflection acceleration.
