I don't know. I used these forums as well as thousands of others to obtain information.
Mr. Phatt is something like a "master transistor" in this forum, so he must apologize to me. I do not know if anyone has ever talked about how to get such OPAMP on this forum.
He probably never had them in his hands !! It's a little sick! He never see original MALAYSIA OPAMP and accuse someone of FRAUD!
It's like you've never seen a Mercedes and said your neighbor has a fake ...
Besides, I also consider numerous fakes like NKT275 transistors ...
But without exaggeration ... If anyone could perfectly counterfeit, it would not be counterfeited by OPAMP just money or documents or something like this !!!
It is sad, he sells these OPAMP not because of the money!
Sometimes I just miss a good word from the buyer saying "Hey! Thanks, I just put it to my Reissue next to the real ts-808 from 1981 and they sound that same! In the end, my thrill is gone!" Now I sell it what they need. If the auction ends, I will not show it again. I will keep them for myself and sell them in 10 years, or i will use it to the other circuit...
I also wrote about my bulb measurements from Shin-Ei Univibe in this forum ... I could tell you exactly what photocells are. From what British radios can you take transformer to the hendrix OCTAVIO effect ...
BUT... I see that people here are the same as in Poland
In Poland, I just could not sell this OPAMP! People write to insult me ... That it's too expensive.... that I'm ridiculous.... that the same opamp on the internet is $ 1 ...
To tell the truth, I see in front of my eyes how the musical knowledge of these years dies with generations ...
It's a sick man ... There's really a handful of people in this world who know what's going on, and this handful of people have an average age of about 65 years...
Another curiosity about the letters above "RC4558P"
"A" "AC" "AB" "AEB" "AED" - this is probably gain.
I did not check in TS-808, but I checked different OPAMP in the buffer and I did not notice any differences.
I also checked difference in the DAC buffer.
I have checked various OPAMP.
But this OPAMP is completely different from everyone! There isn't much treble like most OPAMP! Clearly it has more middle range.
Very warm and pleasant sound at different volume levels!
Greetings...
