[BC] CATV Equipment History

[Xmitters@aol.com]

Hello:

Not a typical topic here, but CATV is certainly a cousin to broadcast :-)

I'm looking for some spec sheets, preferably an entire technical brochure
for some old SKL (Spencer Kennedy Laboratories) equipment and I'm wondering 
if you might have this information in your archives. Here's specifically what I'
looking for:

SKL 263 solid state line extender
SKL 265 solid state trunk amplifier
SKL 222 Vacuum tube trunk amp.

Anything else out of this vintage of SKL line that you might have that would
be easy to photocopy.

I worked on this stuff 30 years ago on a 12 channel system owned by Warner
Cable.

Any suggestions on a good web resource on obsolete CATV equipment that would 
contain a spec sheet or complete description?

Thanks,
