The Z IIB was a 1924 designation and was re-designated in 1925 into Z2B. Most of the Z types had a matching rectifier which were a look-alike of the Z type. The rectifier for the Z IIB was the ZG IIB which had no grid and grid connection. For further data of the Z IIB, see Z2B_Philips. The Z and Zg tubes were replaced in 1927.
