Why Do I Need So Many Resistors? Is It Possible to Reduce?

AI Thread Summary
Removing resistors from a circuit can compromise its functionality, as each resistor serves a specific purpose in maintaining signal integrity and component safety. Redesigning the circuit to reduce the number of resistors is theoretically possible but requires a deep understanding of the circuit's design. Non-trimming capacitors are also essential for stabilizing the circuit's performance. The analogy of removing tires from a car illustrates the risks of altering critical components. Overall, careful consideration is necessary before making any modifications to ensure the circuit operates correctly.

Hello. I wonder if I can take some of these resistors off and make the signal stronger without breaking the rest of the components. Is this possible?

Also why are the non-trimming capacitors needed?

I have a picture attached.

Thank you!

Each one of those resistors is doing a job. Do you know why they are there? You could in principle redesign the function so it doesn't need as many resistors, but given that schematic, they are there for a reason.

Would you ask if you could take off some of the tires of a car and still drive without breaking the rest of the components?

Reminds me of one of my favorite quotes from the movie Amadeus.

The first transistor and associated resistors make up the pre-amp, so if you decide to pound the microphone with sufficiently high volume, you can try omitting Q1 and it's bias resistances.
 
Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...
I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...
Thread 'Beauty of old electrical and measuring things, etc.'
Even as a kid, I saw beauty in old devices. That made me want to understand how they worked. I had lots of old things that I keep and now reviving. Old things need to work to see the beauty. Here's what I've done so far. Two views of the gadgets shelves and my small work space: Here's a close up look at the meters, gauges and other measuring things: This is what I think of as surface-mount electrical components and wiring. The components are very old and shows how...
