Bogen used a lot of 7247/12DW7. They made very sensible compact AF + phase splitter circuits with good performance and wide band, as it's a combo AX7+AU7 in one glass. It's simple you use the AU7 part for what it's designed for, and the AX7 part for what that does best. Some of the compactrons have exactly the same bits inside, but an extra AX7 or extra AU7 triode in there and are extremely well matched. I have loads of all of them mostly NOS or in extremely good condition.

Bogen amps are often mono. Stereo would make use of both halves if one only needed a single 20 mu triode and a single 100 mu per channel.
