August 16, 20215 yr comment_862396 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. Report
January 7, 20224 yr comment_872823 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 ? Report
January 7, 20224 yr Author comment_872830 nope, not mine but may be close. definitely want more information. Report
January 7, 20224 yr comment_872837 Here are more pictures of PCBs that may be an early version. They look identical in terms of layout. Report
January 7, 20224 yr Author comment_872843 that looks very close to my design. no surprise i guess. Report

January 12, 20224 yr comment_873089 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 Report

January 13, 20224 yr comment_873114 This is the latest design might look similar to Stax-D10 but the fact is different. Report
January 13, 20224 yr comment_873115 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🤔 Report

My English level is limited, I don't understand what you mean, do you say not to change the price? Always keep the price of $ 400? Report

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. Report
January 13, 20224 yr comment_873120 @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. Report

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 comment_873124 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. Report

January 13, 20224 yr Author comment_873133 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 Report
