The mid is the most common version of the Philco 90. Many will disagree, but I consider it the best. Some like the early version for the push-pull 45 output but it lacks AVC and the P-P output is pretty much a waste when it follows a plate detector and the distortion it causes. The late version has push-pull 47s but they gave up one tuned stage in the front end.
