hello! i have placed the circuit on the breadboard but it doesnt seem to work.. the display doesn't light up in any way?.. anything you can say about it?
I'm going to make an amplifier but i'm in a dilemma with the proper dimensions of the heatsink of the IC lm3886 ... would a 1.5 x 2 heat sink be enough? the input voltage of the op-amp is around 33-36v
Forgive me for this stupid question (i'm just but a humble beginner) but, um, what exactly is a groundplane? is that the part or the connection that is connected to the ground of the circuit?
Good news everyone :) the original circuit that I made already worked. Thank you very much for all your help! I will still make the 45 W class B amplifier for my personal use ... I find making amplifiers really interesting now :D .
The problem laid under the following:
1. wrong positioning of...
Thank you very much for the links :D . I found one schem which used an all BJT transistor. I think I'll try that one up. Hope all the parts are available in our stores. (45 watts class B Amplifier)
By the way, its okay to supply the circuit with a (33+ and 33- Volts and 3 A) transformer or (30+...
