Cathode bypass was the basis for endless engineering deliberations. Many of the factors could only be validated by laboratory measurements and would not be noticed by the user. Some of those factors are:
1. Stabilizing the IF strip to avoid oscillation
2. Grid matching for the transformer secondary
3. Bandwidth
4. Number of IF stages
5. Desired gain
6. Component end-of-life characteristics
7. Cost
They are all a trade off and determined to assure repeatability over a wide variety of components and tolerances. Often an improvement can be realized by optimizing an individual product.
