If it is ok replace link with say 2k2 pot and set the current through the fuse for 50 to 60 924. I think preamp will just only increase the voltage level of the input signal, but when we split a signal into two actually the current is divided into two. Amazon Advertising Find, attract, and engage customers. Reduce the fuse rating to mA. Hi… plz, provide me the pcb layout. Amazon Inspire Digital Educational Resources. Instead I would like you to use separate filters and rectifier for each amplifier, you mount bridge rectifier and filter capacitors of the value shown in each circuit board.

If things are ok set the current as recommended, and connect 8 ohms speaker and try. Resistors R3 and R2 sets the gain of the amplifier. There was a problem completing your request. For warranty information about this product, please click here.

Hi sir, I orfp planning to make a 2. Power amplification stage based on Q7 and Q8 which operates in the class AB mode. Hi you are correct it should be 33mV. If i connect 25v 5amp ac and 10inch 4ohm subwoofer, what power will actually get when it use as a subwoofr amp? I will use hz lowpass filter before the subwoofer amplifier, do it act as a preamp?

Technical Details

If you try to build, it will not work, as they have not included a lot, what you see is only the tip of the ice-burg. Share your thoughts with other customers. Capacitor C8 is the input DC decoupling capacitor which blocks DC voltage if any from the input source. Hope you have kept R1 at center and R8 at minimum value before switching on your amplifier.

IF unblocked, this DC voltage will alter the bias setting s of the succeeding stages. Page 1 of 1 Start over Page 1 of 1. This give a clue about your problem. Preset R8 can be used for adjusting the quiescent current of the amplifier.


Amazon 2940 Refurbished products with a warranty. This amp will work, but you have to add a filter circuit at the input. With 47 Kohm you get no sound, Q1 and Q2 remains closed.

Learn more about Amazon Prime. Can I use 20pf in place of c4 n c5??

Can dis circuit wrk with bc? It can work with 4 ohms speaker delivering around watts. The amp works fine.

Filter capacitors C8 and C9 must be at least uF, higher the value lesser the ripple. First of all i want to tell you that its a VERY LOUD amplifier even with dual 27V transformer,i will try it with 40v when i buy the new transformers, i have only one question, what kind of pot is the ideal to adjust the volume? Will the preamp be helpful in current gain?
