Well I jacked that up...
 
 1 = a
 2 = g2
 3 = h
 4 = k
 5 = k''
 6 = h
 7 = g''
 8 = a''
 
from the above pic...

I use this to find pinouts

Is this the right way to wire 6832 to 6SN7?
 
6832                          6SN7
Pin 1=A                     pin 2
      2=G2                        1
      3=H                          7
      4=K                          3
      5=K"                         6
      6=H                          8
      7=G"                        4
      8=A"                        5
 
I wired my adapter like this and it's only working with Left channel.

Looks right to me

This looks fine to me. And I am assuming that you remembered that when looking down into the octal base, the pins are numbered 1 -8 counting counter clockwise
 
If you are building an adapter similar to mine, the only things I can suggest is to make sure that you don't have any wire leads touching, your solder joints connecting the leads to the 12 gauge wire posts are good, and the posts are making good contact inside the octal base. You might want to pull out your multimeter and check continuity from the octal pin to the wire lead for each element.
 
Good luck! :)

I'am still having a problem with my miniature adapter still working with left channel only, even i reversed my wiring and using one section at a time or wired right side still just the left channel will play The tube is fine i used each channel separately and it works.It's my wiring that i can't figure out.

No luck selling the LD yet so I unpacked it this morning and now I'm considering keeping it again!

Wanting to try the C3G upgrade. Found a  few online for under $50. @gibosi can you chime in on the difference between C3gs, C3g, and C3m?

C3g that test better than spec are labeled C3g/s in the factory, so both are essentially the same. C3m has 20 volt heaters and a different pinout, so unless you would like to be a pioneer and try these, it might be best to stay with the C3g. :)
