Active splitter PCB

Hi everyone,
Ive done a good search for this in the archives but if I've missed anything due to different terminolgy from my searches, please just re-direct me. Thanks.

I'm chasing some schematics (or even better, un populated boards).
I want to build my own active splitters. 1 in 3 out including the original. All buffered, with 48v, gain/pad on each channel. I'll probably build 24 channels.
I'm really just wishing I could find a 1 channel PCB I could populate and build as many channels as I want. I just don't really have the expertise to design something like this.
Hope to be pointed in the right direction.
TIA

Regards
Jesse Stack
 
years ago i had a design using lm739, zenar on board regulated powerd by 48v supply
and designed for the spectrasonics card racks - if you are interested, i could probably find it with some searching of old papers.... i'm pretty sure i have a circuit board or two lying around
