does the dry in get fed from the same signal that feeds the reverb in?
I love my rail tone amp!

Does anyone has built one of these? The schematic has some unsure values, namely:
- capacitor 0.047 or 0.0047
- Two resistors 220K ?
- One resistor completely left out (identified as "?")

How does one mix the clean with the reverb? It seems they are added, should a pot be between the two unsure resistor of 220K, sending out to "clean out"? Also, it seems the reverb IN/OUT connect in sandwich with the last stage clean tube, such that the reverb would get mix with the 50K pot (upper left). Then it raises a question, namely why you would want a clean tube stage in the reverb section (the last tube at the bottom right)?

Thanks for your inputs. This schematic is not clear at all.
