Just got a Yamaha CT-800 tuner ....no ariel from the prior owner ..its been in their loft for a good few decades ...i've grabbed a couple of the wire in plastic Y ariels from amazon ...reception is rather fuzzy a cleanest Viking FM (Yorkshire) and ok Radio 4 (BBC) a poor Classic FM ...I'm in the UK ...i'm not sure if its the tuner or the ariels (inside) more but going from AFM mode to Mono FM does clean all of them up more ....plus of course i guess giving it some hours running after at least 20 years of loft time might well resolve a few issues ...but for a 1973/4 piece of kit its looks alone are almost worth it plus those illuminated meters and tuning scale ...
