Who's familiar with Audiocraft/Ultracraft AC300?


I found an old Ultracraft AC300 MK2 that my Father in Law left in my basement and am interested in setting it up on my new Lenco L75 turntable. I don't know anything about this discontinued tonearm, is anyone familiar with it? Its interesting because its oil damped and has a dial which seems to compensate for the different compliance of cartridges. Cool! Its missing a headshell though, I'm assuming that I can pick up a used one here on Agon, any recommendations for a headshell to match? Also I'd need a decent (moderately priced) cartridge for it, I already have a Dyna 20XL mounted on my Rega RB300, so I'm thinking of getting a MM, perhaps a Soundsmith Aida, Clearaudio Maesrto/Virtuoso, Ortofon 2MM Black. Any thoughts would be greatly appreciated.
Thanks

Yes. adding damping can (speaking in broad terms) help you out when using a slightly less compliant cartridge than would otherwise be ideal.

When I had the AC-300, my main cartridge was a Benz M0.9 - one of three cartridges in the wood bodied line that was the first step up from the Glider.

The three cartridges in this "model" represented three output levels - the L0.2, M0.9, and H2.0, with the model names reflecting the cartridge's output in millivolts.

If I could, I'd stick with the broad range of cartridges (including Benz) that had a compliance in the 12-15 range.

I used minimal to no damping with the Benz, BTW.

There are likely other fine headshells out there, but the Sumiko is certainly one of the better ones which doesn't cost huge $$$ (as in the Ikeda headshell amongst others). I like the fact that it's machined from a solid billet of aluminum.

Thom, you're right, the outrigger weight solved the problem like a charm. So if I understand correctly, this arm allows you to adjust the damping which allows you to use a wide range of cartridges from low to high compliance, is that correct?
Thom: I installed it last night and noticed that it was tilting to one side. I just read your post and noticed you mentioned the "outrigger weights". Aha! are these the little weights that screw onto the side of the tonearm to balance it? I noticed a few weights in the box, but wasn't sure what they were for. If this is correct, I'll have to try this when I get home tonight to right the ship.
Thanks
Nice arm, I owned one.

Get a Sumiko headshell from the Needle Doctor. While you don't need the azimuth feature this headshell has (you can accomplish this with your arm with the outrigger weights), the Sumiko headshell is machined from a solid billet of aluminum - a nice product which this arm is deserving of.

Congratulations!

Hi Raul, yes these pieces are probably 20+ years old so not much info available on the web, I was hoping that experienced vetrans like you could tell me about them. Jean Nantais, who's delivering my new Lenco tomorrow thinks that his Decca Super Gold is a good match and is bringing it along for a demo. Should be interesting.

I downloaded the manual at vinyl engine and it mentions that the damping oil has a useful life of 2-3 years. I'm not sure if they mean 2-3 yrs in the tonearm or in the bottle? The bottle I have is about 20 years old, I wonder if its any good still? If not, do you know wheere I can get some? its AO-20 High purity silicone oil.
Dear Mikeyc8: That is a very good tonearm as the headshell, here you can find everything about that tonearm:

Rgards and enjoy the music.
Raul.
Updated: I just found an Orsonic headshell, I assume that it was used for this arm. Anyone know anything about this headshell?
