Hey guys I'm stop pre amplifier module here that claims to use the original second-hand transistors and fetes from the original amplifiers whether that's true or not who knows but it was stated in the seller's add and description now this board is way different to all the other boards I can find on the net first impression I thought it sounded a little harsh hurt the is a little bit and was just not all there so some spark or moment of clarity I suddenly had at the time told me to run a 6 J1 12-volt tube buffer after it and somehow it really cleaned up the module I've tried using the tube buffer on other boards and preamplifiers I've got and for some reason this buffet and this JC to clone board just go together like milk and coffee but upon my first board arriving left and right channels were a little uneven having a cyst that it was not my volume pot I decided it was the borg and should possibly try to give biasing and adjusting the DC offset ago as I would imagine the way these things are put together in China and by who is putting them together that they just let them together hope it works and post it to the only reference or instructions I can find for biasing the jc2 board is from a different design similar circuit just slightly different but same principle I will include the picture and diagram of that method and as you can see in pictures below of my board on trying to adjust if anyone could point out which resistor I should be measuring my voltage drop across and maybe give me a little bit of insight into the configuration differences between these two boards and what I should do to mind to achieve what I have to thank you
Let me help you a bit here.
1. This should be posted in the 'Line level' section.
That section is for PRE amplifiers.

2. I think you're asking for help with a particular design,.
So you should tell us what it is, where you got it, with links and schematics.
3. Wall of text.
Seriously.
Kids these days use punctuation as a way to create clear defined sentences and paragraphs.
Dam near no one will try to decipher what you typed out.
4. How about a clear thought out question.
5. If your going to post pictures, try and use a camera, not a potato smeared in vaseline.

Wow I'll remember that
Thanks yeah sorry about that my voice to text is problematic
Hey didn't I repair your DVD player cause the lense had vaso smeared all over it ..
Clean your fingers dude I bet the remote is claged aswell 👍
Moved to analog source.Must've been someone else as I don't have a dvd player sorry.
I have a box full of remotes.
so as soon as one gets mucky I just toss it out and pull out a new one. 🙂
