Ruby Tuby

Request.  This is based around the Runoffgroove LM386 Ruby, but with an IC preamp, into a 12AX7 section, and then into the LM386-N3 power section.  Sounds pretty good in the clips which you can hear at:

This needs a 12VDC supply, so if you're using an unregulated one like the one mentioned in the circuit information then you may want to include a 12V regulator to stabilise it.
