that describes the use of a 6BA7 to improve the conversion gain of
a receiver, but that involves some work as the 6BA7 is a bigger, 9-pin
tube.

The link above describes a 12BA7 to replace a 12BE6 in a table radio
with series-string heaters, but the same idea applies to replacing
a 6BE6 with a 6BA7, although I must admit I have yet to try all this.
Have fun!
