Can some of you shed more light on the cartridge holders Miracord turntables use? Which models use the same cartridge holder? How hard is it to find spare Miracord cartridge holders? Do they need regular anti-corrosion maintenance like Dual cartridge holders sometimes need? If more Duals than Miracords (in any of their brandings) were sold in the USA, are dependable sources for Miracord parts (like cartridge holders) correspondingly fewer?
Also, someone mentioned something about cartridge overhang/alignment being easier on the 50 models than lower number Miracords. Could someone explain that feature more fully?
A really cool feature. On the 50s and some other models, there's a little brush sitting in the way of the cartridge as it is swung over to an LP - a very light brush to knock off lint. That brush come off.
When you pull it, you'll find a point on the end of the pole that it sits on. That's your overhang adjustment!
What you do is to adjust the cartridge's forward/backward so that the stylus tip is directly over the point. Voila! You have overhang adjusted.
As for what cartridge carriers worked with what models, I used to have a list some 40 years ago - multiplay spindles and 45 adapters, too. Alas, lost in a house fire some 16 years ago. That would be quite the research project for someone to reconstruct that list although I'll bet someone already has and we don't know it.
I'd recommend regular maintenance a la Duals, too.
As for why more Dual sold, the answer is that Benjamin, the US distributor, didn't seem to be able to get their list of dealers as long as United Audio. Dual's importer/distributor here in the US, United Audio, was all over the place, big ads in the trade magazines and generally more aggressive in pricing, dealer packages of benefits (advertising co-op $$, discounts for selling above quotas, etc) for working with them. Benjamin seemed to be far more laid back and less concerned about market share - and they lost it, too. Not for poor product but for poor awareness.
