I know I have a NOS one from around 1994. But, I don't have a schematic, even though it kept blowing the fuse in my KSU. I have now fixed the internal issue with re-capping the leads.

Mine came with one, not sure why I didn't upload a shot of it when I got the phone, but here it is anyway:

OK, now where would one be able to find the practice for this phone?

Unfortunately, that I don't know, the schematic came with my phone in the box, and the only other paperwork were key strip cards, a number card and some warranty info, no mention of any practices, probably reserved for their in-house techs at the time... :-\
