[DX] Info

[Denver Wijesuriya.]

Hi Guys,
        Sorry for asking this question on a dx info bull, but I need some
help and info. Hope you will excuse me for this mail. I have obtained a AEA
-Advance Electronic  Appliance contest keyer, model CK-2. I have no
instruction leaflet or circuit details. The keyer works, but is there any
modification I could make, to the circuit that will enable me to alter the
speed setting. Increase or decrease the speed.
        Any info will  be most welcome.
Sorry for the bandwidth.
