Happy New Year!
If you used the correct Pot for gain I don't believe it's the gain pot, it's probably something in the circuit that is wrong.It could be a lot of different things impossible to know at a distance.Before anything you should:-Check all Electrolytic caps values and Correct placement. They are polarized + and - are on the correct holes?- Check all resistor values- Check all capacitor values- Check MAT02 placement, is the orientation correct- Check all IC's Orientation- Check all solder joints and check for possible solder bridges- Measure the voltages across each IC and transistor Pins, do a voltage chart, show usDo you have a friend with electronics knowledge that could help you?
They only have 20v. From the BOM they have 250v.
I really don't think the switchs voltage rating is the issue.But I would change the 48V Phantom Power switch.
Hello All, Looking to build two more of the SSL9k mic pres, and Gustav seems to only offer the 500 series , anyone know where I can get a couple of the older PCBs he used to sell ??Thanks in advance
Thanks Whoops !! what about the edge connector ?
This was a great idea but was overshadowed but the 9K5:https://groupdiy.com/index.php?topic=46784.0
Is there a pretty big sonic difference between the 4k and the 9k?
I would be using these as makeup gain for the DIYRE SB2 summing box. Thoughts?
