A mate has one (an IC400) that he says needs new heads. Mine is even older (a Mk3) on which some previous idiot has tried cleaning the heads with methylated spirit so now they're all pitted. I've tried cleaning them with isopropyl alcohol and they're better but not as nice as they could be. Anyway, I was thinking that Charlie [Watkins] wouldn't have used any more specially-made parts than he had to. They must be bog stock tape-recorder parts. Where do the Revox/Sony/Phillips/Akai R2R rebuilders go when they want a new head?
