Hi all...
Guillaume.. Hope you het to this post..
Recently we were taking about my AR PH2 and the Dynavector cart load matching on another thread..
I finally managed to get a proper manual on the Ph2...with the help of Leo.
Could you kindly help me to interpret the details and what I need to do...
Please could you also home a bit of teaching wrt. Arm and cart compatibility ... What does it mean if your cart weighs a certain amount if grams and how do you know which arms are better suited for which carts etc..
The reason why I ask is cause I'm thinking if mounting the Ortofon kontrapunkt on the Lenco and the Dynavector in the Alphason if I get it fixed oneday.
So this is what I previously posted and found wrt. The Dynavector...
Type Low output moving coil cartridge with flux damper and softened magnetism
Output Voltage 0.3mV (at 1KHz, 5cm/sec.)
Channel Separation 25 dB (at 1KHz)
Channel balance 1.0 dB (at 1KHz)
Frequency response 20 - 20,000Hz (? 1dB), 20 - 100,000Hz
Compliance 15 x 10-6 cm/dyn
Tracking force 1.8 - 2.2grams
DC resistance R=32 ohms
Recommended load
resistance > 100 ohms
Cantilever 1.7mm length, 0.25dia solid diamond
Stylus Micro-Ridge
Weight 5.8 grams
Here are the details for the Ortofon kontrapunkt A
The Kontrapunkt a has an aluminum cantilever that is mounted with a super polished nude fine line stylus. Coils are made from 6-Nines pure silver wire, and the output is as high as 450 ? Volt at 5 cm/sec. by 1 kHz.
The sound picture of Kontrapunkt a MC cartridge is more relaxed, homogeneous and moderate dynamic in the perspective compared to the Kontrapunkt b and with great space and depth in the stereo image.
Depending on the equipment, room and music programmer resistive loads on 100 Ohm or much higher can influence perception of details.
The cartridge seems to work well in combination with various rooms and loudspeakers.
Technical data
Output voltage at 1000 Hz, 5cm/sec. 0,45 mV
Channel balance at 1 kHz < 1,5 dB
Channel separation at 1 kHz > 25 dB
Channel separation at 15 kHz > 15 dB
Frequency range at - 3dB 20-40.000 Hz
Frequency response 20-20.000 Hz ? 1,5 dB
Tracking ability at 315Hz at recommended tracking force *) 80 ?m
Compliance, dynamic, lateral 12 ?m/mN
Stylus type Nude Fine Line / Al.cantilever
Stylus tip radius r/R 8/40 ?m
Tracking force range 2,2-2,7 g (22-27 mN)
Tracking force, recommended 2,5 g (25 mN)
Tracking angle 20?
Internal impedance, DC resistance 5 Ohm
Recommended load impedance 50-500 Ohm
Cartridge body material Stainless Steel
Cartridge colour Black
Cartridge weight 10 g
*) Typical value
Then here is the detail I found in the AR manual..
I hope it's the relevant parts.
I could unfortunately not copy text from the PDF , so had to take pics of the pages.
Can also not upload pics , so here are the links.
The page pics overlaps a bit.

Seems like if I have to adjust , then I will have to do on the TT side to accommodate different loads.
Tx a mill.
