[QUOTE="charles, post: 852301, member: 2759"] Some interesting information; Refer to Telefunken Taschenbuch 1963 Rohren und Halbleiter E88CC CCa Specifications are the same for both as both names appear together in this data book So the CCa may just a very special selected valve for use in for example medical equipment. E188CC 7308 Specifications are the same for both as both names appear together in this data book E88CC/E188CC: There are electrical differences between the E88CC and the E188CC valves for example : E88CC If: 300mA +/- 15% E188CC If: 335mA +/- 17mA I have E188CC valves. Never used one of it. It seems to be a substitute for an E88CC one The other day I found some interesting Siemens & Halske E88CC valves On the box: E88CC 07127 E88CC 6922 The valve itself has E88CC and 07127 printed on the glass. Inside the valve is a metal strip with code numbers. Some of the Siemens CCa valves also has these metal strips with code numbers [/QUOTE]
