Where is the schematic?Hi all!
Do you must give informed schematic for this tube buffer: Yaqin SD-CD3 Tube Buffer?
Thank you and cheers!
thank you!
Oh yes, that's it .... instead of 6n8 schematic to put 6n1p-EV?
What should be the anode voltage + B =?
thank you and cheers!
Socket adapter
Is not a 6n1p a 9-pin tube and the CD3 is wired with 8-pin sockets? You would have to replace the sockets or acquire/make 9 -> 8 pin socket adapters which are somewhat costly.

Why not put in two premium name-brand 6SN7 or 6SN7GT? Done, 2 minutes!

I'll put 6N7GT, it the sound gives ? We need some changes in the schematic?
thank you

This is I think the second or third time you have left out the "S"
6n7GT would be a different tube that exists but is probably wired differently.
You WANT a 6SN7 or 6SN7GT or maybe 6SN7GTB

There seems to be a good commentary on 6SN7 variants here:

There are some comments below about another more extreme MOD idea involving the 7193 single triode tube a MOD I may eventually DO:

Unless his line of questioning changes, I wouldn't give Gost22 the time of day...
Hey guys, how are you all? I have been reading this thread with much interest, I just got one of these baby's and am looking to change the capacitors, BUT...
I've never done this before, I am going to learn how to solder first, then buy the capacitors, but I need help.
1) What wattage should the soldering iron be?
2) Do I need to buy a multimeter, and why and how do they work?
3) Does anyone know what the size of the blue caps are in the tube buffer so I can get correct size ones to replace them?
If I have missed anything out, or if there is anything I should know about changing caps, please let me know, I'm just a novice.
thanks

Sorry to be boring, but my advice is "don't do it". The risk of damage is quite high if this will be your first soldering job, and the most likely outcome is no change at all in the performance of the unit. The second most likely outcome is that you break something, and then have insufficient knowledge to fix it.tazzo said:
There is a circuit diagram in this thread (I forget where). That will tell you the value of the caps.
Good idea, and these types of lessons are best learned from someone locally; not online. Electronics are fun and a good opportunity to learn, but can be very dangerous if you don't know what to do.
Mono-Block question cont'd
the tubes used in this buffer are dual triodes, and each tube has those triodes wired in parallel in the circuit, so, in a way you are already getting both segments of each tube, per-channel. If you found a way to mono-block as you say, I doubt you would hear anything much different. Now, it is more likely that sonics could be impacted/changed some by tube swapping, or modding to take the various other options like 6F8G, {or if I had a CD3, maybe the 7193}. Or just try better 6SN7s. 6n16b-v might be a simple experiment, solder some leads to a pair, or use socket-savers to adapt them.
