Playa de la Malvarrosa

First multicache in Valencia. It is a 3 km walk from the port of Valencia (where in 2007 the America's Cup takes place) to the Playa de Malvarrosa. It contains three stages.

It is necessary to visit the three stages to get the final coordinates.

Go to the coordinates above. There is a technical monument. How many gears do you see (number A)? The unknown number B is the number of the electrical machines. Stage 2 is in a distance of A*(B-1)*DS(A)-1.5*B m heading A+7 °.

Now you are at a monument to an famous valencian actor. How many spikes has the star (unknown number C). In which year was the monument built (unknown number D)?
The coordinates of stage 3 are:

39° xx.yzz 0° qq.rrs
xx = A
y = B
zz = SC(A) * C - B
qq = A - B - SC(D)
rr = A + B + C + SC(D) + 1
s = SC(D) - B

The third stage is a sculpture by Antonio Marí made in the year 1998. Count the animals (unknown number E) and the waves (unknown number F) in this sculpture.
The coordinates of the cache are:

39° Eh.kll 0° qq.mmn
h = B + DS(D)
k = C - F
ll = A + C + F
mm = E * A - DS(D) - B
n = F

Special note:
DS() is the digit sum of a number.
E.g. DS(47) = 4 + 7 = 11
The direction is true north (not magnetic).
