The Tektronix 504 is a monolithic oscilloscope with a bandwidth of 450kHz [[introduced in 1960]]. It was introduced at the same time as the 503, and is mechanically and electrically identical, other than the vertical amplifier. The 503 incorporates two identical phase matched amplifiers with true differential inputs to support X-Y operation, whereas the 504 contains a simple ground referenced vertical amplifier. Due to the low bandwidth and need to keep the selling price low, neither the 503 or 504 include delay lines in the vertical signal path. | The Tektronix 504 is a monolithic oscilloscope with a bandwidth of 450kHz [[introduced in 1960]].

Both scopes use the same CRTs. The CRT circuit uses a single [[5642]] to generate the -3000V cathode voltage. | Both scopes use the same CRTs. The CRT circuit uses a single [[5642]] to generate the -3000V cathode voltage. | ||
