This was Bush Radio's first VHF/FM receiver. The VHF41 was a poor performer on FM especially in the London area back in the days when the transmissions were originally horizontally polarized.
A really good aerial signal is required to obtain reasonable listening volume and tuning drift over a period was also a problem. None of my customers used the FM facility simply tuning to MW/LW.
A private wire to Wrotham may cure the problem!
Most front ends with twin EF80 valves were poor except the Philips who managed to do the job correctly. Good luck with it, nice looking radio. John.
