The 7904 makes extensive use of custom integrated circuits and hybrid circuits, inter alia, the [[155-0064-00]] 470-ps output amplifier, [[155-0022-00]] analog multiplexer for channel switching, [[155-0059-00]] HF amplifier, [[155-0095-01]] and [[155-0095-03]] differential HF amplifiers, and [[155-0067-02]] SMPS controller. | The 7904 makes extensive use of custom integrated circuits and hybrid circuits, inter alia, the [[155-0064-00]] 470-ps output amplifier, [[155-0022-00]] analog multiplexer for channel switching, [[155-0059-00]] HF amplifier, [[155-0095-01]] and [[155-0095-03]] differential HF amplifiers, and [[155-0067-02]] SMPS controller. | ||
The 7904A includes [[155-0173-05]], [[155-0175-05]] and [[155-0178-05]] amplifiers. | |||
The signal path is completely differential and all of the internal wiring is 50 Ω coax. The CRT ([[154-0644-05]]) has distributed vertical deflection plates. | The signal path is completely differential and all of the internal wiring is 50 Ω coax.
