Help with the volume control - model 70
#4

Hi Ron and Terry

Thank you both for taking time to reply to my question.

I will switch the outer leads on the volume control and see what happens.

To answer the question from Ron, I purchased a kit from Mark Oppat which, I understand was put together for the express purpose of replacing the dual control.

It came with the two resistors which I mentioned and a single volume control. I do not know the resistance of the control and wondered what value it should have for this usage.

The chassis is in the radio at the moment and when I take it out I will measure its resistance and let you know.

Thank you again for your help.

Joseph

PS Mark did supply me with a circuit diagram showing the changes and it look like the new circuit calls for a 10 M (meg?) volume control.
