Hi Carlos,
The LFO speed is controlled by three pairs of capacitors, one pair for
each 'range' switch position:

C1A/C2A = 2n2
C1B/C2B = 47n
C1C/C2C = 680n (= 0.68u)

The biggest cap values give the lowest speed. Thus to slow the LFO
down, replace a pair of these caps with something bigger (or you could
simply solder a cap in parallel with each of the chosen pair) -
doubling the cap value will halve the speed. These caps are either side
of the top-most TL084, though the silkscreen printing is partially
obscured by other components.
