If you get the "Sorry, the file cannot be displayed. There seems to be a technical issue ..." error when trying to view an image, a workaround is to click on the cog icon in the upper right side of the media viewer, and then select "Disable Media Viewer". We are aware of the problem and are looking for a solution.
It is similar to a 535, but without the second, delayed timebase. Instead, it has a range of horizontal magnifiers from ×2 to ×100.

The vertical amplifier consists of a 12BY7 differential amplifier followed by a 6DJ8 cathode-follower, followed by a 6197 differential (common-cathode) output stage that drives the 200 ns L-C delay line, which drives the vertical deflection plates of the CRT.
Trigger pickoff is taken after the cathode follower stage in the vertical amplifier. There is a 6DJ8 differential trigger pickoff amplifier followed by half of a 6DJ8 a cathode follower, buffering the trigger signal.
The trigger circuit is a 6DJ8 trigger amplifier followed by a 6DJ8 Schmitt trigger. Triggering can be from the internal pickoff or from an external signal or "line" trigger, from a 6.3 V tap on the power transformer.
The 533 contains a 53 °C (128 °F) thermal cutoff. The high voltages for the CRT, +8,650 V and −1,350 V, are generated by a 60 kHz Hartley power oscillator and five 5642 high-voltage rectifier diode tubes.
