early instruments) or a [[6DJ8]] tube (in late instruments).
The delaying timebase on the 535 (non-A) supports delays up to 100 milliseconds.
The 535-S1 supports delays up to 1 second.
The 535A supports delays up to 10 seconds.


The 535 is functionally the same as a [[545]], but with a simpler, non-distributed vertical amplifier.

==Internals==
 
===Power Supply===
 
The 535's power supply provides regulated outputs of −150V, +100V, +225V, +350V, +500V as well as a +325 V unregulated output for CRT HV section.
 
The Power supply section is very similar to a [[549]]. It is a all Tube design with the using the following tubes


[[Category:Specifications needed]] ''please add''
[[5651]] as  Voltage Reference Tube <br>
[[12AX7]] as comparator<br>
[[12B4]] as  -150V Series Pass Tube<br>
[[6080]] as +100V, +225V and  +350V Series Pass Tube<br>
[[12B4]] as  +500V Series Pass Tube<br>
[[6AU6]] as error Amplifier for all rails<br>
