Hi dear

These two type pot is'nt your matter .

Both work as same .
First picture show basic pot or single turn
Second show the precision pot or multi turn .

Type 2 use for fine tuning pot position ( usualy 10 turn for full range tuning ) but not usualy use in md devices.

Can you give more information about your noise bproblem ( both side pcb pictures ... schamatic used for tl 12000 and etc )


Please contact me in pm for more responses

?is what I need to invert the other transistor

is what you can give me the exact positions of the multi-turn potentiometer with
changer
