82E01 Unknown Mods

Hi guys,

Looking for information on any known / standard modifications carried out on the 82E01 Channel Input card.

I’ve received two E series channels for repair, one of which has 48V permanently enabled and a pad in place of the traditional phantom switch, and both of which have faulty line input - one which is missing components, and the other has a modded sub-board added on which is in a state of disrepair.

Any advice greatly appreciated!

I think the mod board may be the "line in to meters" mod? If you drop me a PM I can try to help with these two.

Cheers,

Hi, I would be interested in this as well.
Have the same Input Cards with the little extra PCB mounted on each card.
No further Documentation in my Service Manual...

Thanks,

If I find or work out any info I'll post it here - it would be in my "4000 master collection of circuits" which I assembled over many years at SSL, but sadly I was a good boy and left it there when I left  :(

Aw, thank you! I'm winding down my hours in the day job now so hoping to have more time to devote to places like this.
