Do you have any info on how to use the BT 878A / cx2388x directly with the raw signal ?
I haven't digitized tape in more than 15 years now, but would like to get all the quality possible out of them before they kick the bucket (if they haven't already).
edit: this board seems to have updates on the subject:

and the linux driver for more control over cx2388x:

and a google doc with instructions:
