Hi all, following my previous post about LD2 there is another problem that came up. When using Phantom Power, Everything works fine for a short while and than the signal fades away quite rapidly. The Voltage on IN+ and - is down to 28V when the 48V switch is engaged. What confuses me a bit is that on the kit C1 (100u, 63V) is packed but the partslist with C1 on is crossed out and on the new one C1 is no longer there. I have put C1 in initially and thought that this might cause the problem and so I desoldered it, but the behaviour is the same.
Any help highly appreciated!
Best regards,
Guenter
