The decks I'm referring to are solidly made, have good, if slightly 'lively' tonearms that are absolutely inert with a good MC fitted, yet delicate enough for a high compliance Empire, Shure or ADC of old. Bearings are state of the art and the idler drives are legendary. Ignore them please, as it'll help keep them affordable for those that know them better Later Duals have gone the ultra-low-mass (and thinner deck plate metal) approach and are very different, although Funk have gone the same way with their tonearms in terms of low mass these days and claim it's not an issue.Classicrock wrote:The arms are a little limited and have that slide in cartridge mount thingy. I think some of the belters are sort of hybrid idler with a toothed belt. I have a 506 inherited which I will have to service at some stage and bring into use. Not even close to a GL75 or Thorens 160 in SQ from memory.
The 601 belt drive, and all the Dual belters before the small plastic hub came along, is properly designed with an inflexible belt, a large diameter driving hub and a solid cast and balanced aluminium platter, not a thin shaped 'plate' as on the later and current ones. No speed hunting at all and no motor drone or harmonics coming through that I can tell.
