Description	PP4101 Tungsram = E443H Philips. By model of the very similar USA-types PZ or 47 from 1931, with the E443H Philips now introduced output pentodes in Europe with equally 250 Volts screen and plate voltage, it also brought the 7k-ohms load-standard to Europe which remained until the end of the tube era. The former E443N required 400 Vp, but extra 200 Vg2 [J.R. 2003-01-19] Text in other languages (may differ)
