I have no interest in the company other than as a valid parts supplier. I will be placing another order for their rotary encoders, but not for these resistors. I only use carbon comps for grid stoppers and I already have a few thousand! </div> <div class="e_p"> Some, but not all, carbon comp resistors exhibit a slightly nonlinear resistance / voltage characteristic, and therefore can impart a unique distortion signature.....hence the belief that they are magical. </div> <div class="e_p"> They are also non inductive and therefore good stoppers on G1 in a tube, and the gate in a mosfet. The use as a stopper does not impart any voltage drop across the resistor, therefore does not create measurable distortion. </div> <div class="e_p"> Most film resistors use a spiral cut in the film to trim the resistance value, and therefore are slightly inductive. This is usually not an issue except with low value resistors on mosfets, and high Gm tubes with good RF characteristics.....In these cases a stopper can actually MAKE a part oscillate. </div> </div>

Rules about cashback: 1. Valid time: ALLPCB cashback activity will end on April 1st. 2. Capped amount: The capped amount of cashback for each account is $5,000. Each order can get a maximum of $2,000 cashback. That means every author can get $5,000 max. 3. Cashback range: The cashback activity only covers the corresponding PCB order. The order amount for other combined payment products will be invalid. 4. Clicking your own promotional link will be invalid. The same email address, shipping address, contact information, and phone number are all recognized as the same account. 5. ALLPCB has the final interpretation right of the cashback activity.
