This tone control have nothing special, the quality is only that it will work very well for the ones that do not like 250 Hertz and do not appreciate the boominess of 100 hertz amplification.
It is, made with that purpose, centered in 35 hertz...the bottom of hell groovy punch in the bills.... alike a punch in your stomach...to make your home shake, as people is making the 25 hertz insertion, sometimes less to make you feel afraid. DVD use those tricks all the time.
Of course this is personal...but if you cut 400 hertz and 250 hertz in the music scene....or at least reduce those damn frequencies, sound turns better immediately.
You will see three groups containing two 47 resistor in series each one....this is a 100K potentiometer adjusted to center position.
You will have 15 dB gain in 30 hertz....... 13 dB gain in 10 hertz and only 5 db gain in 100 hertz... so, if your speaker is small, or not a good tunned enclosure....you will move control and nothing will happen..... before send this tone control to trash..... imagine the possibility your speaker can be a trash.
Mid frequency adjustment is around 12 dB centered at 1Khz... this one can include the damn 400 hertz amplification.... aaaaagh!..i do not like...will change latter.
The high frequency is old styled.... 12 Kilohertz centered with 12 dB, plus and minus.
Circuit have too much sensitivity, so, if you can make it better...please...you welcome to suggest and post modifications.
Transistor not informed, as you can make your own choice....will work with 43 Volts DC...and maximum undistorted swing will not reach more than 6 Volts peak to peak.
80 mV in the input is enougth to distort 5 hertz tone...but...if you cannot hear...not so big problem for your ears..but your amplifier will gain heat as a hell!...if it cannot amplify 5 hertz...garbage can is a good place too...hehe.... today i am very bad!....yeaahhh!... real bad!
The capacitors will change the bass centered frequency..... 33N plus 33N is good to make the traditional old styled sound.
You can try 47 plus 47N
You can also use 56N plus 56N.
Or the 68N i am using to wake up my dear neighboor that uses to make some noise in my life.... some gift i give him every morning!.... 300 watts of earthquake in his home. (put speaker against your wall, if apartament... and make pressure to vibration transference to the wall...use the middle...not a corner...not down....put speaker pointed some side..open front baffle...and your back making the enclosure pression against the wall...neighboor will be happy! hehe (terrible!)
He came to me....i told ya that i have some defective cable....that i do not know. where's the damn problem...but that he can hold that sound i produce in the evenings as he make a lot of noise too (ahahahaha)
hehe, some revenge is sweet as honey, and must be done with a good smile in your face.
Now i am finishing two turbo AKSA, using 65 Volts DC each one...i will put them in a bridge mode....hummm 80 volts RMS will be very interesting as a gift to my neighboor.
I am thinking in turn some 15 inches speaker into the wall, some distance not to touch the wall.... make some holes and screw some speaker into the wall.....Yessssss!!!!
