I meant the broken 100uF/100V output capacitor due to long time recording.
The input capacitors are used whether phantom power is on or not, right?
I read on the PCB, the input voltage indicated is 13V~15V.
And the stock 120V->12V AC transformer is measured with 13.1V~13.4V.
I got another new 110V->12V AC transformer measured with exactly 12V or 11.9V
Interesting the new 12V AC transformer has a more defined sound.
I wonder if the lowered input voltage damage the circuit?
