Hi I have a Bush VHF61 radio that works on long and medium waves but not on VHF. In this case I have tried replacing ECC85 & EABC80 valves but to no avail. All that I can hear is a background hiss but no stations. Wonder if I should do a modification using a ECC81 valve (changing heater connections) since good ECC85 valves are nearly impossible to obtain (due to bulk buying)? However when switching from a.m band to f.m, I can hear weak stations, but these soon disappear?
Cheers
Mike
