Krell FPB400cx coupling capacitors question


Does anyone out there have instructions for engaging the coupling capacitors on Krell amps? I have a Krell FPB400cx, ARC ref 2 MKII and First Sound Ultimate tubes pre-amps. Is it ok to run between those? Please advise. Thanks guys.

I have a FPB700cx and used several tube preamps with it. If you're nervous, check the DC output of your preamp with a good (Fluke) multimeter.
There is no minimum-the lower the better. My Bat preamp measured 0.002 Vdc and I haven't had any problems. I would guess anything below 0.01 or so would be fine but I'm not an expert. I talked to Krell about this and they were totally non committal.
