He may be right about the ECC85 but not for the reason he gave. Valves do not 'go dim' when they fail unless you crack one and then it won't light up at all! The heaters are probably fine but just not as visible.

More likely it's just low emission...worn out. However don't forget you need an aerial for VHF, preferably a proper dipole but you should be able to receive something with just a piece of wire about two feet long if everything is OK. If not then try a new ECC85
