For small value capacitors less than 1 nF, polystyrene is your best bet. Download my parts list to see the components I used to get really good sound quality from these amplifiers.
tds2003 The components you use in your amplifier will have a major effect on the sound quality. Circuit Basics on April 13, at 5: Consent to store personal information: Metal film resistors are the best choice for audio. Use the formula below to find the resistance values for your desired gain:. This is to reduce the length of the traces connecting the capacitors to the chip.
Email me new tutorials and very occasional promotional stuff: Electronic circuits is a total new hoby for me and I found this site and it is a good start. You can use any type of box depending on what you can find, but metal enclosures are preferred since they offer shielding from interference amplificaeor by fluorescent lights, radios, and cell phones.
For the larger value capacitors, amplificqdor are the only option. The cutoff frequency is calculated the same way:.
Here is a bridged amplifier PCB layout for a single channel. Divakar Pathak on June 24, at 6: The bass lacks a little punch, but the overall sound is very well balanced.
Like the stereo amplifier, the bridged amplifier has a low pass RC filter at the output. Sy Do on April 13, at 5: Mabey you can say something about this point before I solder.
Both amplifiers sound great. So all frequencies above I have a question about the bridged Amp: Leave a reply Cancel reply Your email address ampligicador not be published.

I wanted to ask, what is the resole that you used, high voltage capacitors in a circuit that will work on a supply of 12 Volts. Capacitors C7 and C3 in the left channel and C9 and C10 in the right channel are the power supply decoupling capacitors.
The cutoff frequency is:. Now I did the final check befor starting solder the bridged amplifier.

If you have any questions, be sure to let us know in the comments…. Juan on October 3, at 7: I have the questions for this project: Eva Finch on July 27, at 3: The left channel gain is set by resistors R1 and R2, while the right channel gain is set by R6 and R7.
Actually there are two different datasheets. I am for several weeks ordering the parts from the partlist and they are finally at home.

I do not mean it critacal but I see some differences in the pictures from the amplifier relative to the PCB before soldering.
Capacitors can be very expensive if you go for the high-end audiophile brands.
