560-series scopes

The 560 series scopes which were introduced with the 560 and 561 in 1961 were tube scopes that began to introduce some solid state circuitry. They use 2-series or 3-series vertical plug-ins and 2-series or 3-series horizontal plug-ins (exception: 560 only takes 2-series because of weak power supply).

560-series mainframes contain neither delay lines nor amplifier stages, requiring the plug-ins to drive the CRT deflection plates directly, at the disadvantage of needing to calibrate gain or sweep when swapping plug-ins.

These scopes are compatible with 560-series plug-ins.
