Hello everyone,
I just finished Electrically restoring my Mitchell 1260 Lumitone radio lamp .
First off the start the set works well even without alighment done yet .
But I did notice there no real midrange lots highs thou what I am thinking is to change some coupling cap values and maybe a a capacitor or resistor to make this set less tiny .
Here is the Audio Section any suggestions far as maybe a RC circuit or maybe a LC circuit .
Far as this set I know that poor little speaker is not much .
So capacitor and resistor values are as follows
C4- 005 ufd
C6 ,C7 - .01ufd
R6 - 6.8 megs ohms
R7 - 220k ohms
R8 - 470k ohms
Sincerely Richard
