my meter was $6.50 out of hong kong and i thought that was enough to pay. my schematic does have a 22k potentiometer but it does not have the r17 resistor fitted so maybe it does need the 22k pot will not know until i get this finished as to wether it needs that resistor or not depending on the meter used as you said earlierso i have 20 k 25 k and 50 k pot to try in this circuit as i,m thinking resistor 17 was put in place to compensate for the pot size being small in the first place and thah r17 resistor was added to the pot to give it more resisatance???
i do now have the 22k pot also to try with my schematic and have given you the schematic updated version of the original idea so you can now see what i,m building
