I have a question. I'm looking at my Rider's print of the 42-395 schematic; it says the output tubes are 7B7's, yet the print shows them as 7B5's.
And what is the difference between a 7B5 and a 7B5E??

Thanks in advance.

It is a misprint. A 7B7 is an IF remote cutoff pentode and a 7B5 is an audio output tube equivalent to an octal 6K6. 7B5E????????

The 'E' version of popular US types are European versions. Usually the gounding pin has different connection.
