CV1053 (CV1053) = ARP34
Nikolaus Löwe

Liebe Röhrenadmins,

die CV1053 ist identisch mit EF39 und ARP34. Meine Quellen sind die Unterlagen zu einem britischen Empfänger, die Web Site, sowie andere Web Sites.

Mit freundlichem Gruß,

Nikolaus Löwe

Vielen Dank Herr Löwe,

Es ist getan!

I have also added the other tubes that meet the CV1053 specification according to the official documents.     I am slowly adding all the CV types and their data, but have at least a thousand entries to make with all the equivalents!

Thank you for drawing this to our attention so that we can improve the accuracy of the data.
