Yes, John. It is by comparing these two models that it is clearly visible that in the more expensive Philco 655 model, two 6F6 lamps are used in the output stage in a triode connection, while in the cheaper 645 model we see the same lamps, but in a standard pentode connection. So we can conclude which type of connection is best for correct sound.
