Cheers Steph, well I'm only happy to be proven wrong while learning. Now thanks to you I am a little bit less stupid.
I bought mine as a Thorens TD160 'Super' as it said on the top plate. But with time, curiosity induced by the urge to convert my SME3009 'Improved' tonearm into heavy mass, I started to venture inside and tweak some my turntable and understood that it was a TD160 'Super' only on the outside and a TD146 on the inside.
Oh well, now I know. And it doesn't really matter since after all the conversions, improvements and upgrades I did on it I truly enjoy it's look and more importantly what it dishes out more than ever before. Tim
