These are some DIY Gainclone and audio project that I have completed. (If the links to files are broken, please post a comment and I will upload the files again. Links do not get broken by my doings, it is the hosting sites which remove them for no obvious reasons)
I will put more details later, but for now enjoy the files.
NOTE: (If the links to files are broken, please post a comment and I will upload the files again. Links do not get broken by my doings, it is the hosting sites which remove them for no obvious reasons, I guess all HOTFILES links are dead)
LM3886 Gainclone Altium Project Files
OPA549 Gainclone Altium Project Files
A High End Pre Amp and Sound Refiner based on BUF634 and OPA2134
DIY PGA2311 based Pre Amp (Utlimatley I will convert this project into a tutorial to DIY a PGA2310/PGA2311 based high end pre amp, and will have everything, including the source codes and tutorial on customizing my firmware to your needs, and even making a firmware yourself. )
Here are the schematics of my PGA2310/11 based Pre Amp with four input selector
Firmware along Proteus Simulation File and cof file (taken offline due to ongoing improvement)
So now the Photographs of the Pre
Main Board of the Pre Being Populated
Another View of the Board
Power Supply section and Quad RCA
Fully Populated Board, only thing missing are the ICs, which is the next step.
Buttons and Rotary Encoder and I.R Board
20×4 VFD will look pretty on the front , finally made it work. Damn Thing requires too much current, unless you could control its brightness function, it screws up even LT1083
An Amplifier is Born
Here is a pictorial visit to one of the AMP that I build based on above mentioned LM3886 gainclone design
PCB of Pre Amp OPA2134 and BUF634, populated and PCB.
Another view of the OPA2134+BUF634 pre amp PCB.
DS1802 based volume controller, populated PCB and unpopulated PCB.
DS1802 based Volume Control with buttons soldered on the bottom side of the PCB
Pre Amp OPA2134+BUF634 populated PCB, along DS1802+OPA2134 and Input/Output RCAs
RCA Jacks Mounted on PCB for Input and Output.
OPA549 populated PCBs one with a gain of 10 and the other with a gain of 14.7
Another view of OPA549 based gainclone PCBs.
LM3886 Gainclone, PCB of Gainclone, power supply and RCA Jacks. One Two channel populated PCB
Another view of LM3886 Dual Channel Gainclone, with IC’s mounted on heat sink.
A Closer View of LM3886 on populated two channel PCB
Being Fitted in the case, Final Decision, is to use LM3886 gainclones. OPA549 gainclones could rest for a while.
Thanks a million for this, I appreciate the info
Mind-blowing article bro. This kind of is just a enormously nicely structured piece of writing, just the awesome info I was looking regarding. I praise you
Hi, Links dead
I’d appreciate if you let me know which link is dead so that I could upload the file again.
Hi, Links for DIY PGA2311 based Pre Amp
Ok uploaded the files again
the files are available at the link of “Schematics”
Thanks
Hi there, the first 5 links are all broken. (The links to the LM3886 and OPA pdfs.) The projects look great though.
CHeers,

Ah thanks for letting me know.
Lovely DMCA, all file sharing services going offline, even legitimate contents have been taken offline.
Will try and upload the files over the weekend , hopefully.
Right. One of the things never talked about by content police: the removal of legit content. I appreciate your efforts.
Cheers,
