So far as I can make out from the available photo's....If it's an EAF41 the diodes anode is shorted to the cathode, that aside the EAF41 and the EF41 pentode wise appear to be more or less the same, they appear to be pin compatible. The Rmuseum schematic snippet shows pentode only for the IF amp, eg EF41, the valve given in radioworkshop is an EAF41, maybe that's what was fitted as found as it would be a sub for an EF41.
