Hello to everyone,
First of all, I would like to thank everyone from this forum for their great work.
I started diy stuff one year ago, with simple guitar gear.
I'm a sound technician, so I moove to studio gear.
My first try is a green preamp, 4 channels.
I've just got a problem on it, and I was searching on the web, apparently no one had this before.
I've read that 3 caps need to be 63v, others can be less.
My power supply delivers +14.8v/-15.2v.
On all channel, the "green" 10R resistor burn everytime.
On all channel, the second "green" 47u caps blow up the frst time I powered the unit.
On all channel, the first "green" 47u cap seems to be not fine...
They are elna 47uF 25v.
I will replace all caps with higher voltage, but if anyone has an idea on this, I'd be happy to know it.
have a nice day!
