537

The Tektronix 537 is a storage scope from the 500 series that never left the prototype stage. It was probably made in 1960 or 1961. It is similar to a 531A, but with the following changes:

• replace the CRT with a Hughes Memoscope CRT
• add some extra circuitry for the storage CRT
• remove the delay line

It uses the 120-120 power transformer.
