Great topic, comming in a bit late as usual, but here goes:
I'm wiring up a Wolf replica, and having trouble understanding the diagram on dozin.com. (see link below)
From your explanation, the send should be through the stereo tip, returning through the stereo ring. It seems that this diagram is showing the opposite.
Also the return is going into the second lug of the volume pot, then feeding the tip of the mono jack from the first lug. Isn't that usually done in the other order (input first lug, output from second)?
Thanks for any response.
