CDC Electronic Work Shop The Amplifier Adventure III part 1 Making a tone controll

[KRC1023]

If i was to build this, there is only one thing that i didn't get from the video.

do you put the tone control in the speaker circuit before or after the amplifier.

and WHAT was that first song you used.

Very nice tone control! It works great. I never knew of the logarithmic and linear pots, I just thought they were all the same. (except those that can turn around multiple times).By the way, how's your original amp (the one with the relays) going? Still in service?

@CassetteMaster This new amplifier i'm building is going to replace the one with the relays, I had to take a couple of them out to fix up something else, but one day I'l get some replacemant relays and get it going again.

What amplifier circuit have you picked for the project ? There are some out there that are just crap and a waste of time cuz they don't work.

[CoolDudeClem]

@TheElectricnoob I found a schematic of a 90 watt amplifer (100 watt if a good power supply is used), I'll show the actual schematic of it in the next video, I'm currently building 2 of those, for stereo of course, I have one built and even though I couldnt find the exact output power transistors specified in the schematic, it seems to work well, great sound quality (and that's without the tone controls), and goes quite loud, so it's looking good.

A little correction of the schematic; the leftmost cap (470n) should be 474 instead of 473.. :) Nitpicking, I know, but hey.

Interesting as always!

@Kankki1 Easy mistake to make there, I must have missed out one of the 0's

What do you need this controls for? I know what they are for, but wouldn't it be better if you make an amplifier with only one control and it would be volume control? So the idea is to make a good amplifier with good speakers that don't need any controls except volume control. The best audio components should sound fine without any tone adjustments. What speakers are you planning to use with the DIY amplifier?

[CoolDudeClem]

@BeeOwGeeDeeAyN I'm sure my amplifier would sound good without tone controls, but it's really because there are times when it would be a good idea to turn down the bass, so as not to annoy anyone, or when one of my recordings isn't too good I could ajust the treble and bass to compensate for it. Most of the time I'll probably have them set to the middle, my bookshelf speakers do have a good sound, and I have a pair of vintage 70's hi-fi speakers, there quite loud, but need a little bass bost.
