Dual 1219 tonearm and Pickering Xv15 with 750 stylus

Postby Celticguitar666 » 12 Oct 2010 19:14

Are these a good match? I was reading an article about cart /tonearm compliance The xv15 has a value of 35 would this be a good match with the 1219 arm?
I tried tio find a way to calculate this and could not. any ideas or help? please excuse me if this is a stupid question or mentioned somewhere else here. The sound I hear form this setup seems excellent and I tested it with a TT test record with good results

Hello Dwight,

I found a nice diagram from an old Dual brochure. With the known mass and compliance of your Pickering system, adding about 1 gram additional mass for the mounting screws, we get:

So, that Pickering system with the Dual 1219 results to 7.4Hz resonance. That's just a teeny-weeny-tiny bit below optimum, according to common doctrine (allowing 8 - 14Hz).

I'd say, that Pickering fits just OK.

With the now known set of values for both the Shure M91 and the Pickering XV15, The "Effective Mass Calculator" of the "Cartridge Database Tools" results in 6.5 - 6.7 grams effective arm mass for the Dual 1219.


Greetings,
Dirk

When I got my 1229 a couple of years ago, it had an XV-15 with a D400 stylus. It seemed to be a good match

I say the XV15/750 is in practice a low compliance cartridge!! I'm using it with a rather mid-heavy, modified lenco arm, and i get the almost ideal 12Hz resonance frequency. It should hit 12Hz or more on your Dual, which is great.

Edit: My experimental findings are:

Static (0Hz) compliance = 12Hz
dynamic comp @100Hz = 10cu

Hi Flavio,

Is this your current main configuration? Or do you have 2 Lencos, :) one with the Technics Strain Guage and one with this Pickering.....

Inquiring minds want to know and what are your impressions / comparisons........ :-k :-k

I have 3 lencos but only one is installed. I just switch cartridges and realign everything again.

After my simple mods (basically increased counterweight mass to 170g), tonearm effective mass, not including cartridge (6.5g), seems to be 9g which is surprising.

I think that what is happening is that the rubber v-blocks are doing significant damping on their own.

With the EPC-451C cartridge, i get 8Hz resonance mass. Best explanation is that static compliance is rather high, 35cu. It certainly deflects more with the VTF compared to the Pickering cartridge.

As sold in the US under the "United Audio" umbrella , I think the 1219, and I know my 1226 came OEM with a Pickering XV-15. I'm nearly 58, and as a young teen I thought Dual=Pickering! Anything back to the 1000 Series Duals' with a gimbaled tonearm should be pretty happy with a XV-15 under it, or something newer and better. If you use the brush on the VX-15 stylus, (1 gram and some dampening factor ala Shure M97e), it's almost "ideal". Make sure you have a good stylus and enjoy the mellow sound of the XV-15, but it can kick-it on Heart, Queen, CCR , Boston, Eagles, and more. I love ole Blue Eyes with the VX-15/750E. Some worn or slightly abused LP's do better with the 400E stylus, the type of music and VTF make a difference too, I've found.

I also believe some of the Dual 1200 series tables were originally purchased with the Pickering XV15 on them. I am pretty sure that that is how the original owner of my Dual 1229 received it.

As for the D750 stylii, I have read somewhere that some of the generics of that stylus are real crap. What generics of it are of reasonable quality, does anyone know?

Dual 1200 series turntables ruled in the 1970s. My college roommate had one and it was outstanding turntable.

silphium, I can give you some generalities, because we can't be positive who makes the "generic" styii. The "Made in Japan by the finest craftsmen" stylii sold by LPGear and Garage-'A-Records seem to be very to very, very good. Some even come in their little jewel-boxes marked "JICO". Your's may not. My 750E did. It was a flat-out BARGAIN! ($35 as I recall) The "Made in Europe/Switzerland" stylii are reportedly not so good. They may or may not be made by Pha........, but again, we can't be sure. Rule of Thumb, Japanese stylus good, European that's not NOS Pickering (available but $$$$$) not so good. Your mileage may vary, patent pending, do not used while wet, dispose of properly, always wear seat belt.
