I just updated the reflux condenser housing with a longer one. The original one was 12" and the new one is 14-1/4". I believe the shorter one suspended the reflux condenser too close to the vapor take-off. It seemed to require that I run the reflux condenser hot (slow water flow) otherwise the take-off rate would drop. This should fix that and make it not finicky with water flow which is the way it should be.
