I find that very hard too believe. What are you actually asking Google? What are your search terms. I typed in "audio power amplifier circuit" and selected images. There are pages and pages of possibilities. Pick one that looks good to you. If you want an RF Amp then modify your search.
PS Google is very good but it is not a mind reader and can only respond to specific queries. Possibly you kept using the term "schematic"? Leave it out.

Related to Find the schematic diagram for a power amplifier (for repair)

1. How do I find the schematic diagram for a power amplifier?

There are a few different ways to find a schematic diagram for a power amplifier. One option is to search online for the specific make and model of your amplifier, as many manufacturers will have the schematics available on their website. Another option is to consult a repair manual or service manual for your amplifier, which may also include the schematic diagram. You can also try reaching out to the manufacturer directly and requesting the schematic diagram.

2. Why is it important to have a schematic diagram when repairing a power amplifier?

A schematic diagram is a visual representation of the circuitry and components in a power amplifier. It is important to have this diagram when repairing because it allows you to understand the layout and connections of the circuit, making it easier to identify and troubleshoot any issues. It also helps ensure that you are using the correct components and following the correct steps during the repair process.

3. Can I use a generic schematic diagram for any power amplifier?

No, it is not recommended to use a generic schematic diagram for a power amplifier. Each amplifier model may have different components and circuitry, so using a generic diagram may lead to incorrect repairs and potentially cause further damage. It is best to find the specific schematic diagram for your amplifier model.

4. Are there any risks involved in using a schematic diagram for amplifier repair?

There can be some risks involved in using a schematic diagram for amplifier repair, especially if you are not familiar with electronics and circuitry. It is important to follow safety precautions and make sure the amplifier is unplugged before attempting any repairs. If you are unsure about any steps in the repair process, it is best to consult a professional or do further research before proceeding.

5. Can I make my own schematic diagram for a power amplifier?

It is possible to create your own schematic diagram for a power amplifier, but it requires a good understanding of electronics and circuitry. You will need to carefully examine the circuit and draw out the connections and components. It is recommended to only attempt this if you have experience and knowledge in this area, otherwise it is best to use the manufacturer's provided schematic diagram.
