hello,
after many tests with my 1073mic pre,when I want to indicate 48v with a led it makes a (big) problem (transistors=bc184 starts to oscillate :evil: )
I'm using a simple ON ON switch.
I explain me : I use the same position on the switch to supply 48v at the xlr input and to have the correct supply to the led via a resistor.
As soon as I put 48v on, the led illuminate correctly and...I have some oscillations.... :?:
is this the good reason or is problem coming from anything else?
Any idea :?:
I've made before a search on the forum and here is a result :
