From Electronics (magazine) advert:
Type 561-A Vacuum Tube Bridge, can measure all the inter-electrode parameters of all the tubes over extremely wide ranges of variation.
It is accurate as well as being direct reading, and its flexibility makes it applicable to any tube now in use as well as any that are likely to come forth within the next few years.
