I have a KNIGHT T-175 10/6 meter amplifier that I purchased at the Dayton Hamvention. I can not find any information about the two coils that came with the kit.
Well, you are learning that without eHam.net and helpful amateurs, your purchase would have been a bust. The guy who got your $$ is Very Happy.
You are aware this was sold as a KIT ?

It sounds like Charlie, WA3UTC has the details on the TWO PLUG-IN Coils (6, 10) that you need.
ARRL Handbooks of that era also had DIY Build amplifier articles of similar designs.
The Knight T-175 Amplifier was offered in 1967 in the late days of Allied Radio (Chicago), before the Tandy/Radio Shack purchase in 1969/1970. The Knight Kit division was on 25th Avenue, Melrose Park, IL -- east of my QTH a few miles.
Jim Fisk, W1DTY(sk), the future editor of Ham Radio magazine, reviewed the Knight T-175
for Wayne Green's 73 magazine in October 1967, when the T-175 was first offered for $99.95 !!http://www.nostalgickitscentral.com/allied/73-index/articles/T-175%20610-10-67.pdf
