setting that was decided upon for loading MM cartridges. A calculation will be required to arrive at the appropriate resistor for the required load. The load capacitance of the interconnect Clearly the resonance shows up in all cases except minimal capacitance. Calculate Loading The Moving Magnet input has its own impedance generally equal to 47 Kohms. The CA 640P has plenty of gain for HO MC cartridges and enough for many LOMC cartridges as well. Here, the load was set at 47k and 200pF while the inductance The Yamamoto MC cartridges represent one of the best deals in all of analog. I understand the 47k is meant for MM cartridges, and my dealer recommended 100. That includes interconnect! While complex ordering can, in some cases, lead to stacking slightly more items, it is also more difficult for the people fi… Charge Weight (in grains): Cost per Pound of powder: If you're unsure, or just want options, check as many boxes as you'd like. This is a fairly simple container loading calculator: it allows you to calculate how many items of the same dimensions and weight (optional) you can fit in a single shipping container. and preamp are lumped together (Ca). In an MC cartridge, this suggests that the inductance has a negligible effect on the cartridge's internal impedance at low frequencies and only a modest effect at the top-most frequencies, not enough to affect dramatically the choice of an ideal load R, if no SUT was used, but obviously the impedance will increase with frequency ad infinitum. Plugs in next 2 pics are $2 or less, have the advantage of minimal metal, resistor pictured is a cheap metal film, if you like the results of your changed load, perhaps use a better quality resistor of whatever flavour you might prefer. Performance. coil (5mH) has terrific bandwidth, although the ultrasonic peak is quite pronounced. The 47K number, btw, is not capacitance, it is the recommended load RESISTANCE (47,000 ohms) for many MM's, and approximately corresponds to the input resistance of many or most phono stages or preamp phono inputs, that are intended for use with MM's. The use of Titanium in the MC Windfeld Ti has provided a further improvement to the overall rigidity of the structure and the cartridge weight. Material connection (partnerships) information available at http://ultimatereloader.com/about/, Subscribe to Ultimate Reloader Reloading Blog by Email, Mr. Bullet Feeder Caliber Change: 9mm to 45 ACP on Dillon XL-750, XL-750 Bullet Feed SOLUTION (Double Alpha Extra-Short Powder Bar), TESTED: NEW VihtaVuori N555 Creedmoor-Class Powder, Unsolved: 44 Magnum Over-Pressure Mystery, RCBS Lock-Out Die Part II: Setup and Maintenance, RCBS Lock-Out Die Part I: Theory of Operation, Reloading Safety: Powder Check Systems Overview. The MM cartridges deliver a more solid performance on comparison with the MC cartridges but the MC cartridge is capable of giving higher frequencies, hence providing a better sense of openness in the output. Mated with an Ayre p5xe phono pre, I have the options of 100, 1000 or 47k. So, the cartridge “sees” the 47K load resistor at the input to the preamp through the transformer as being 470 ohms, which is arrived at by dividing the resistor value, 47K, by 100, the impedance ratio. The Sierra load manu is ideally suited for load density analysis because powder charges are arranged under an estimated velocity column. Poll: What’s your number one reason for reloading? While bringing resistive loading to the set of user-adjustable parameters in the MM cartridge-preamp interface clearly adds a useful degree of freedom to the sound optimisation problem, doing so purely on the basis of the cartridge's electrical specification and attempting to flatten out the electrical frequency response is ill-advised. Some MC cartridge also has higher outputs and can work on standard phono input but it is still not higher than the MM cartridge. KAB P.O.BOX 2922 PLAINFIELD, NJ 07062-0922 908-754-1479 PHONE 908-222-3442 FAX EMAIL:info@kabusa.cominfo@kabusa.com That's the reason I put it on forum. Contact ultimate reloader by clicking here. I have a Rega P5 TT. MC cartridges have less inductance than this example (chosen to highlight the issue), and so the typical loading I'm sure this has been asked and answered before, but I'm struggling to figure out what is the proper load setting for my AirTight PC-7. Then select your bullet weight, powder manufacturer and powder type. The next plot shows the 5mH 10 ohm cartridge loaded For a 1:10 (20dB) step-up, the imedance is transformed by a factor of 100. Find what you need in four easy steps. The reason for the Moving Coil is so "insensitive" is that it has a low internal/generator resistance, which makes the MC cartridge more "immune" to what we load it with. To calculate the cost for a load fill in the fields. Too much damping with the 470 ohm load pulls the response down too quickly. The Load Computer tries to predict a Charge which will nearly fill the case and will produce a peak pressure between 40,000 and 50,000 CUP. Calculate Voltage Gain (From Input and db Gain) Calculate Cartridge Input Voltage (From Output and db Gain) db Gain Calculator (Voltage/Current/Stylus Velocity) db Gain Calculator (Power) Step Up Transformer Loading (ohms) I heard or read a good advice once, ... (Optimal Game Weight) formula gives you the weight that your cartridge bullet is capable of taking down, if used properly. MC cartridge load impedance is usually 5-10x the output impedance of the cartridge as specified by the manufacturer, 1x-5x for cartridges used with transformers. Yamamoto MC Cartridges. Most MC cartridge manufacturers provide a recommended range for load impedance (or resistance). Currently it only supports simple stacking, meaning that each item will be placed next to the other, no complex rotations or ordering. How do you find the proper load impedance and what happens when it's wrong? Become a Load Data member, access over 300,751 load recipies LoadData.com is a powerful search engine that allows you to search an ever-expanding database of loads. Here's the resulting frequency response: There's a small lift at 7~8Khz, not enough in amplitude to be detectable (less than 0.5db) caused by the high inductance of the cartridge, but most importantly, response at 20Khz is 8db down Do you think these cartridges sound too smooth in the treble? A place where audiophiles and audio companies discuss existing and new audio products, music servers, music streamers and computer audio, digital to audio convertors (DACS), turntables, phono stages, cartridges, reel to reel, speakers, headphones, … With small bore cartridges, the pressures will likely be on the high end of this range. Select your cartridge type from the drop-down list. with 200pF and a variable resistance. That file also describes one way to estimate the case capacity of a custom cartridge, including a calculator. KAB P.O.BOX 2922 PLAINFIELD, NJ 07062-0922 908-754-1479 PHONE 908-222-3442 FAX EMAIL:info@kabusa.cominfo@kabusa.com YC-03S / YC-03M Wood Body MC cartridge. value of 100 ohms is usually quite reasonable. a bandwidth of over 100kHz. This is why MC cartridge You have both Varmint type bullets OGW and Big Game OGW below. The use of Titanium in the MC Windfeld Ti has provided a further improvement to the overall rigidity of the structure and the cartridge weight. While in theory this may give an acceptable noise specification for the preamplifier, it does not provide the necessary damping for the MC cartridge (this 47kOhm input resistance is the “compromise? Calculating Filter Life The next part of the analysis is to calculate how long the filter(s) will last with an inlet solids (dirt) loading of … Poll: Where are you finding reloading primers and powder? Select your cartridge type from the drop-down list. JB, in my experience MM cartridge specs do usually indicate recommended load capacitance. This is now approximated by: Determine the bandwidth of your system using the following calculator: This is a confusing subject for many because of the nonlinearity of the impedance transformation. / Cartridge's Powder Capacity = Load Density. Into a standard 47k loading the AT 440MLa is a tad too strident in the treble and the Denon DL 160 a little too lean. The function of a step-up transformer is to raise the output of the MC cartridge in order to be correctly handled by a Moving Magnet phono section.
