|This simple tone control can be used in may audio applications. It can be added to amplifers, used as a stand alone control module, or even built into new and exciting instruments. It's one IC construction makes it a very compact circuit, as only a few support components are required. Plus, it does not use a dual power supply. This means that the circuit will run from 9V to 15V (although the bass will be a little weak at 9V). The circuit is by Robert Barg and originally appeared in the Think Tank column of the May 1998 issue of Popular Electronics.|

|Hi I have a karaoke model Plardin Pl-1029. It is a 10k watts amplifier, Fm radio. I just can't find the right IC for the tone control section of it, because I don't know what is the part number of it Do you have a schematic diagram of this model. Preferably on its tone control section?.|
|try to experiment more,improvised it. do your best find the best possible as you can . but be carefull or you may waste your money in a split seconds.if you damage your audio amplifier and power supply if it explode.|
|you can use that input captain transformer to enhance bass response of your amplifier.not directly on your amplifier but to your tonecontrol circuit specifically.as i explained it already. that's a tradeschool (ctu) trade secret, highschool and college since the 1980's. my schoolyear 1982-1886.csat-cscst.|
|@julius Hi im from cebu too, i am still a beginner in electronics, i built an "bass & treble amp" as we call it here i am interested in putting a "captain transformer" to the amp, can you please give me a schematic on how and where to connect it to my amp thank in advance :)|
|how to make your standard horn/dome tweeter w/permanent magnet a super tweeter. use 2.2uf/50v non polar series filter capacitor then parallel an inductor to the ground.then series again another 1uf/50v to the tweeter. now parallel tweeter's two terminal's with another inductor. the data of the two inductor's is 50 turns #24 magnetwire on a 5/16"diameter 4.5"long ferritebar.you can also reduce/adding another number of turns of your coil.or changing the value of your capacitor.with my data it's already tested.|
|as i mentioned this input captain transformer is most likely applicable to andy collinsons baxandall type,tone control circuit.you can also use this input captain transformer to any tone control circuit similar that of andy collinsons tone control circuit.you can also connect a switch, to turn it on and off.don't also forget to parallel a capacitor to the input captain transformer rated at .01-.2uf/50vmylar capacitor for brilliant treble effect.try also different combinations for improvement.|
|this input captain trnsformer is most likely applicable to andy collinson's baxandall tone control cicuit.just parallel the input captain transformer to the 2nd stage transistors emitter,and the other terminal of the input captain to the ground.remember the input captain transformer has five terminals.one side has 2terminals and the other side has 3terminals.just chose 2terminals per side.and the other side is of no use.also parallel your input captain transformer with .01uf -.1uf mylar capacitor for brilliant treble effect.....the effect of this input captain transformer is a rubberlike and extremely deep bass effect.|
|my advice,when incorporating an input captain transformer to your tone control circuit , try puting a switch in series with it.it really works, a very deep and a rubberlike bass effect.and for a brilliant tweeter effect .also parallel your input captain transformer with a mylar capacitor rated at .05uf-.2uf/50v.try different combinations,experiment.|
|for perfect tweeter series filter capacitor use .5uf-2.2uf /50v non polar or mylar 630v capacitor for horn/dome tweeter. .22uf-.5uf /50v non polar or 630v mylar capacitor for piezo electric tweeter specially motorolla.and parallel your tweeter an inductor/coil directly.the data for the coil is 50-130 turns#24 magnetwire on a 5/16"diameter 4.5"long ferrite bar or your old junk A.M.radio ferrite bar.|
|the perfect filter capacitor for any tweeter is .5uf-2.2uf/50v non-polar capacitor and parallel your tweeter directly with an inductor or coil.the data of the coil is approximately 50-120 turns #24 magnet wire on 5/16"diameter 5"-7"long ferrite bar, available at any electronic stores.|
