Hello dear experts!
I'm having a hard time trying to figure out what's going on at the mic input here:
http://schems.com/bmampscom/art/art Tube Pre M3 sch.pdf
Could anyone please explain me what's going on with polar electrolytics connected minus to minus? Does this config let the signal pass through?
Next. What are the diodes? I know it should be some kind of the input protection (limiting), but how does it really work? Why do you see two diodes connected to +33V and one to the ground?
And more importantly, is there a way to optimize this circuit (i.e. remove unnecessary complexity)? I'm of the opinion that this circuit doesn't sound really good, so I'm looking for a way to mod it.
Could I just remove the 47uF caps and first diodes and replace the 100uF ones with 33uF ?
I'm not very good at electronics, but usually it's not hard to understand the basics with some help or googling. This time I have troubles. Hope someone can help.
Thanks in advance.
