Dual 45 tubes in a Philco 20?

After you ensure it is electronically sound enough to fire up, measure the fil V for the output tubes with no tubes in the sockets. If it is 5V, it's a 71A output model. If it is 2.5v, it's for 45s. Another possibility is that a model 21 chassis somehow made it into your 20 deluxe cabinet.
