And be prepared to change a lot of resistors as well. I picked up a 48-482 a couple of weeks ago and have started working on it. Some resistors have opened completely and others radically changed in value. Despite this, the radio actually worked to some extent as I received it.
Be sure to check the plate load resistor of the 7W7 RF amp tube, R502 (33K). It was open on two different sets I checked. With the open resistor the FM will work but the sensitivity will be low.
