Ledgendre - I think my original post wasnt clear enough it seems .
Firstly , I dont think I mentioned any term " Strapping " or meaning parallel ..but if I did , I appologise for the confusion .
However ..if its resolution only that this is for , well then thats very simple to cure with a 10 turn pot ( Spectrol type ) like ive used . They work brilliantly . I realise the fixed resistor allows you to place the standard pot somewhere near the ideal range , so adjustment can be found without being at the end of the pots electrical range ....
I was just checking that it wasnt for some other purpose - hence why I asked . For instance , I couldnt see why the pot wasnt a 10 turn linear spectrol with approx 50 k ohms . Ive experimented with a standard 270 deg linear pot , and found the sensitivity not to my liking . Its far to easy to move it well off target . However , a 10 turn pot , mal adjusted by one turn , doesnt make the setting wildy different . Ive proven this , as one amp I have fitted 10 turn pots to , and the 2nd has for now , the standard style 270 deg pots . I'm definately changing these out for the 10 turn ,, and accompanying them with the Vernier adjusters to boot . They , at a glance , can be checked , and also referenced for where & how much shift is happening over time . I m just applying my common sence to the controls , but at the same time , asking to clarify the original intentions - just to be sure . Thankyou
Stu

I understand that a fixed resistor around the pot is used so that if the pot fails... - jeffreybehr 23:44:13 09/19/06 (2)
