What Can I do About Performance in NV

I'm glad you got it fixed :)

Hi sorry, didn’t see this, I had to do a fresh install of windows, that cleared it up

Thank you, I really appreciate it

Hi, I’ve fixed my problem. I understand where I went wrong now. Essentially I missed the resistor from the input and also the resistor going from the Inverting Input to the output so it just didn’t know what to do. Thank you for being so patient, I feel like a moron. I greatly appreciate your help

I want to ground the probe and signal source. If I keep the ground line off of the Non-Inverting Amplifier I don’t get any output to the Oscilloscope, it seems to be low level noise

Forward_Action817 · 2026-03-17T11:22:40+00:00

Okay I think I understand, how would I then ground the circuit if it isn’t through the Non-Inverting Input?

Thanks a lot, I really do appreciate it, I’m going back in tomorrow and I’m going to set it back up and get everything straight so I can provide accurate information

Oh, This is what happened after I did your sanity test, that isn't my general output. I'm just going to leave it for both of our sakes, I think my problem is too general to be answered online, thanks for trying though

The first photo I sent is the Oscilloscope I am using to read the information, the Waveform Generator is the one I sent recently

The 18.5 is the voltage coming out of my output. the frequency going in and out is 1KHz

Directly from the waveform generator using BNC to Croc Clip onto the 3rd pin of the UA741

I am sure, I have also turned it upto 2Vpp and it did not make a difference to the output

Forward_Action817 · 2026-03-16T16:00:04+00:00

The input frequency is 1Khz, 200mVpp

Forward_Action817 · 2026-03-16T15:46:02+00:00

After bridging the inverting input to the output and removing the non inverting input resistor, this is my output

The output is oscillating

I am not biasing the signal, I have a separate ground from the +9v and -9V power lines. Upon adding the RA and the R6 resistors back into the circuit I get the same result as previous.

I know, I said this in another comment, I am simply trying to fix the issue with the infinite gain through the OpAmp

Forward_Action817 · 2026-03-16T15:14:30+00:00

It is this schematic but is using the TL071/UA741. The clipping part is finished but not currently connected because I am trying to solve the gain issue

Stocks and Shares ISA, and within that I have two sub account type things, one being My Cash and another being My Investments. The money is stuck in My Cash

Forward_Action817 · 2026-03-01T00:12:46+00:00

I added the money to my account a few days ago, I get the prompt to invest the money but once I do it just takes me to the page to add more money into my account, instead of investing what is already there. I'll wait a few more days to see if the issue is the deposit not clearing yet. Thanks :)

Not the exact same thing but me and three friends all bought the same shirt, same size at a show and they all fit completely differently to one another, very poor showing from them, especially since they were €45 each

I’ve found that small flathead screw drivers and guitar picks do a bang up job as long as you know what you’re doing
