Oh my god...what's happen with the security? I don't see any strange behaviour on my construction...perhaps SMPS is not isolated?
Tell us more...
Thank you

What happened? People use your designs with great success, and prefer them.
I hope you will rethink your decision. Whatever security issue you might have would be a serious task for the forum’s moderators.
I hope they will contact you if you haven’t contacted them already.
All the best, I appreciated your contributions very much and hope to see you back.
Regards, Gerrit

I am a hobbyist who like to share his projects to stimulate users to try to build it themselves. But a lot of projects end in endless discussions and non constructive remarks. These cost me to much energy and are no fun. In the 90’s I was active on hififever.com and tweakers.nl,00’s on zelfbouwaudio.nl and roerenundhoeren.de, 10’s on diyaudio.com and it is time to move further. All these forums changed over time to places were users were afraid the post because of other users who have as hobby to only make comments but have no building/project contribution.
If you focus on people that are negative by just being so, i can see you loosing interest. And everywhere you go there are people like that, just out of boredom or spite. But you are not doing these projects for them, it's for the people that actually want to make them, and love to use them.
I for one follow your projects, i find them interesting and have ordered and received pcb's to make in the short future (especially purifi tube buffer), and wanted to pitch you an idea for that as well.
I’m saddened by this news Koifarm and hope you will reconsider your decision. I appreciate your contributions to this forum and enjoy reading about your projects. Yes, there are few members that like to “push one’s buttons”, but for the most part this forum is friendly and very helpful.
Thank you for sharing your universal tube preamp!

People like you are precious, i understand your point of view but may i kindly ask you to rethink situation? Anyway, thanks to you the same.
In open forums like this one, negative and toxic elements are always around and co-exist with positive ones. Isn't this the world we are living in? Koifarm can take this forum out of him, but he cannot take the world out of him. And fortunately i have saved his gerber files and schematic posted earlier....😀
All the best Koifarm, whatever your final decision may be. Thank you for sharing your designs.

I will take a timeout to evaluate my projects and publish them again if there are no issues.
My pcb is nearing completion soon. I didnot notice that this board is any more dangerous than the Baby Huey EL 34 pcb that l build a few years ago.
Perhaps Koifarm can share more details as to his decision.
I am grateful to Koifarm for sharing his work here and his many other projects such as the MA 2070 board that l am also interested.
I thought Koifarm is very innovative and give us solutions for problems faced by many ordinary diyer
Thanks to Koifarm once more

Excuse pserci but what do you mean with
1) "what's happen with the security?"
2) "I don't see any strange behaviour on my construction"
3) "perhaps SMPS is not isolated?"
and what do you think is the wiring diagram and the image of the pcb in post 1?
Without a technical survey and a possible solution, I didn't really understand the meaning of your post and its necessity.
Best regard
Stefano

I always suggest to build only th eproject with the test lab published.
This is a warranty that the circuti it is not only on simulation or quickly built but also certified so each one would to build it know which is the results.
This not mean that the sonic rsults will be perfect as we think but that it is running fine.
Too many simulations here without any real buildings!!1
I have presented dozen of project on Audioreview nagazine in Italy and some also here always with the minimun of verification on lab in addition with schematic
I understand perfectly Koifarm

Hi Stefano, i've assembled the project with fully success (you can see my previous post about relay), I've used the SMPS PSU mentioned by Koifarm, and supposed that the only issue could be the input/output isolation caused by this chinese SMPS.
Circuit is actually working very well.
Thats it...
Walter, i assembled circuit using original PCB layout (as per the gerber kindly provided). No issue at all, sound is good for my poor ears and this construction allow a series of easy modifications that could be experimented with little modification on the configuration.
