August 16, 20214 yr I had to pause this project for a bit, but I'm picking it back up now. I've had issues with some of the batteries I've been testing. I'm going to try and get a clean set and test with my current 3S balancer as well as a stock (ebay) 3S battery protection circuit.
January 7, 20224 yr I saw a portable estat amplifier on a Chinese e-commerce platform and it looks very similar to kevin's amplifier, Is this the commercial version ?
January 7, 20224 yr Here are more pictures of PCBs that may be an early version. They look identical in terms of layout.

January 12, 20224 yr Can't tell if you're justifying stealing the design or getting mad that you got exposed, maybe it's both

January 12, 20224 yr By the way... I have been made aware of that the mini T2 is marketed by a company unknown to me. They want $ 7,000 for it. It is an example of a villain's business model. Edited January 12, 20224 yr by JoaMat

January 13, 20224 yr This is the latest design might look similar to Stax-D10 but the fact is different.
January 13, 20224 yr Kevin Gilmore also said that Stax D10 is a D class amplifier, I design a Class A amplifier expects to have better sounds. I hope so that🤔
January 13, 20224 yr @HVRV Please, Never ever make any changes within a quote. I urge you to make appropriate changes in your earlier posts.

I hope so that🤔 Absolutely not. Stax D10 uses apex high voltage opamps and is class a/B with limited voltage swing. other amplifiers out there use class D amp driving transformers. birgir has a couple of them. they suck. If your amplifier is indeed $400 then i want to buy one NOW. Since the design is virtually identical to my design there is no reason for me to build one when i can buy yours.
January 13, 20224 yr @HVRV, When you quote someone’s post it will appear in your post marked with the members name and time of the post in its own “window”. In that window you can’t make any changes. You have quoted me and written something I haven’t said. I don’t like that.

A representing the formation is the push-pull design and D represents digital circuits such as op amp. In addition, I don't know how to mail my product to other countries. If you have a better way I am willing to provide my products after the Chinese New Year's Day I can determine that my product does not contain taxes and freights, stabilizing in $ 400👐 47 minutes ago, JoaMat said: @HVRV, When you quote someone’s post it will appear in your post marked with the members name and time of the post in its own “window”.

January 13, 20224 yr In any country who thinks opamp is a digital circuit can not steal anybody's design. You could be the merchant. If so, I am going to buy an amp from you too.

January 13, 20224 yr Author here is my original schematic from january 2021. there are minor changes in the production version. Might as well let everyone steal it. electrostatportable.pdf
