Re: SSL 9K & 4K (E Series) 500 / 51X NEW BOARDS Mic Pre Thread 2011

Hey guys,
I have a little issue with my 9ks
voltages at IC22 & 29 (NE5534) on booth of my boards are not were they are supposed to be.
Pin 2 has 11,2 VDC
Pin 3 has 16 VDC

i measured these values with all socketed ICs removed from the sockets.

is this normal behaviour?  :-\ would be great if somebody has a idea where i can hunt the mistake.


cheers  :)

D305 and D306 are backwards on the silkscreen of V3.9.  There is also a mod to adjust the gain of the HPF.  Send me your email in a PM.
Best,

Hello Bruno, just finishing 4 of your 9k congratulations they are fantastic.

Thank you
