How did you connect (20)? No, it should not be hot at all. It sounds like you may have (20) backwards? That would not only cause the hum, but if connected backwards, that cap would not only get hot, it will explode sooner or later.

The positive lead goes to the junction of resistors (13), ( 18 ) and (19) plus a couple other connections - see schematic; the negative lead goes to chassis ground. If it has been connected backwards, it is ruined and must be replaced.

Ron number is fine it's number 44 that gets warm. I am getting one station but poorly.

Sorry number 20 is fine it's Cap 44.
