I'm restoring a 38-7, and the original 2Mohm volume control/loudness circuit  was replaced by a very cheap non-split pot that is falling apart. I'm embarrassed to be asking this, but I came across a thread somewhere in this forum about an equivalent circuit for the loudness control that could be constructed using two 1 Meg pots.  I've got the pots now, but of course in the meantime I can't find that link.  Can anyone direct me to the thread that showed a simple circuit for the loudness/volume control that was made from 2 coupled 1M pots? 

I'll post an update on how well it works if I can find it again.
Thanks!!
