I would like to disconnect it, I only use the MIC PRE filter and EQ.QUEEF BAG said:one standard response would be the guys at 81series.com
but you will have to motivate them, and that is not always easy.
that's probably true of any good tech that has that info.
if they know how to fix old neves, they're really freakin' busy.
what info you need? the only info i can get to is the 8248/8128 modules.
main module connector is different, but i think the mic pre, filter, eq, etc.
have the same pin outs for the small ribbons.
repair or racking?

You need at least 3 volts over the regulated voltage in order for the regulators to do their job. I suspect that you didn't take your regulated supply high enough for that to happen.

I'm a little late to the party so I hope this gets seen. I'm starting the exact same project and I would be very appreciative of the same resources. I'm a new member so I also need a pm from youI agree, with Mark, you need MIN 3 volts minimum over the regulated voltage.
I've finish the racking of my pair of 8108 this summer, this channel strips sound realy good.
I used the fabio PSU to feed two channels and a summing board so +/-24v, +48 and +5v for the relays and the leds.
PM me your email, i have the schematics of the pream/filter/eq it can be usefull for do the job.
Cheers
