I notice there are two variants of this model - one has 5 valves ( 2 x ECH21, EBL21, AZ21, EM4) -the other has six valves ( ECH21, 2 x EF22, EBL21, AZ21, EM4) the circuit diagram shown for this model is the 5 valve variant whereas the valve line-up shows the six valve version. The six valve verison has a larger physical cabinet (and was much more expensive when launched). I am working on this larger verison but cannot find a correct circuit diagram. If anyone knows where such a diagram might be found it would be very helpful for me.
Many thanks, John
