I think my thread look like dirty link. It is my first local web sharing.
When Andrew T. asking for the file, I serch inbriefly and choose one,that's all
Now I change the web sharing to MediaFire.

hi tommy55
Very nice work. 🙂 I think it will be a great source of information for those starting DIY audio.
I have had a quick look through and I think you should double check all your bridge rectifiers in the schematics.
Hey, I even noticed a picture of one of my amps, if you want a higher rez picture PM me your email address.
regards

attach your data pics & whatever to your post.
Don't use remote servers.
You have no idea when they will go down, No idea when they will cease operation.
You will likely not track the links into posterity and update dead links for us hear.
DIYaudio will do that for you. Attach.

Nice pdf document tommy55
Just 2 questions:
(1) Did you play with various tube buffers before you decided on this specific one?
(2) How does the sound compare with and without the tube buffer?
Thanks

Hi johancraftech
Thank you for interesting.
For your questions, the answers are :
1. No, first I intend to use tube buffer to protect my amplifier and my speakers from various input sources I'd changed as its name, only few hope this will give a tube sound.
2. I'm not sound expert, for me only a little bit change. I think if someone want to improve sound quality he should be better to see pre-tone, equalizer or etc. from tube or solidstate to modify sound.
Don't forget the purposed of buffer, both tube buffer or transistor buffer, sound improve is a little profit.

Dear All
After Greg Ernskine asked me to check the symbol and node of rectifier diode in the schematic, I did check and found the mistake of symbol drawing.
So I rectified the file and upload the new file through MediaFire already.
Sorry for my mistake and Thank you Greg Ernskine very much.
I want to confirm about the symbol vs. real parts, here are the pictures.
These pictures will clear all the problems.
