Better Homemade Resistors. With a non-magnetic core, the inductance is negligible at audio-amplifier frequencies. If a 1 ohm resistor is placed in series with the cap (or the caps internal resistance increases by 1 ohm) then the ripple current flowing through the cap produces a greater ripple voltage across the cap than if it wasn't there. The efficiency of this amplifier is 70%, distortions at cut frequency were at most 0. From 1 Ohm to 10 milliohm , there are 64 values and 10 resistors of each, meeting your various working needs. So take a second look at the ripple voltage with and without the added resistor. Make sure all switches are in the 'zero' position (make sure the little metal contact thing is touching the 'first' resistor of each switch, the 'input'). A 100W MOSFET power amplifier circuit based on IRFP240 and IRFP9240 MOSFETs is shown here. The 1 ohm goes in series with the "load". With a power supply of ± 30V the mosfet audio amplifier can deliver 45W on 8 Ω and 70w on 4Ω. 5pcs Wirewound Ceramic Cement Resistor 5 Ohm 10W Watt 5% 3+ day shipping PYLE PLMR24S - 3.
