That's an interesting looking amp psu with those fat caps and those nice big diodes that rectify the ac. 🤔 I might get some perf board and experiment with caps, diodes, and psus.

Interesting stuff even if most of the technical jargon flies over my head. I like that you perform these advanced tests because my only test equipment are my ears lol. I will simply avoid the kits that you determine are 5h!t lol lol. I do wish that there were repercussions for false advertising. I agree with the other viewer's cat o nine tails suggestion. Cheers amigo. BTW, I switched over to INAV 7 on the OX7 quad and everything is going swimmingly. I should get my fpv monitor tomorrow and it should help improve the production quality of my vids. Cheers amigo. I hope you're having a happy Christmas season. 🍻 🎅 👍

I know that Class A amplifiers can get very hot but would a Class A amplifier give a much cleaner output compared to that of a class B or a Class AB.

I like my kits flat too. My tube amp has no equalizer. I want to hear the mix that the musicians intended.

Your speed of build was certainly impressive!! So you saying your Christmas dinner was better??? What is the noise floor of your equipment? Have you ever done a loop test of your equipment? Eyeballing your graphs - you noise floor seems to be around -105db?

The only thing I have checked is scope grounds do not ground to the USB from AD2. When I test I use my laptop with battery and not connected to the power supply. I understand that may not clean up everything its the best I can do. I use a Dell Precision M4800. I may use ARTA to take a look at some stage. As you know ARTA has a process for calibration and the outputs it displays can be depending on many factors. The point is when I test I use the same setup on all DUT's so all will incur the same positives and or negatives from my setup.

Hi, You should be able to test the thd etc of the same equipment you use to test the amps. Instead of plugging into the amp input and then amp output to the Digilent - plug directly in into your Digilent bypassing the amp- that way you loop the test equipment, and should be able to test the THD of your equipment Would be an interesting test @@Elecifun

@@zoelong6021 After reading your comment I played around connecting outputs to inputs. The Audio Analyser Suite requires a load impedance in Ohms to run the THD tests. It won't run with 8 Ohm load as no power, distortion exceeds limits.

That's a pity then - I don't know the Digilent equipment, most analysers allow for loop back testing. I mostly use Arta, its accurate, lots of support online as used by many - and also cheap. Will keep watching your channel...who knows what nice goodies you may uncover?@@Elecifun

@@zoelong6021 Are you talking about connecting AD waveform gen to AD scope input and measuring? What sound card are you using, I see Xonar in video. Which one? I have been thinking about getting a sound card for my computer and testing with ARTA. Would you suggest a sound card.. Sound Blaster X5 or AE-9 ? both have great specs.

Sir, I have this feeling that the guy that encouraged you to buy this amp was perhaps a shill. 🤔

Lol.. not sure a vicious anything will change anything.. His test setup is different to mine and I didn't buy this because of his claims. I bought it to take a look and see for myself 😉

@@Elecifun Why not have a go at building some speakers? You've built heaps of amps. Why not try your hand at building a cabinet and getting some speakers? Cross over for 3 speakers. Even if it takes a month it would be a fun and interesting build. I'll be building some speakers after I pay for other more urgent things like my teeth.
