Here is information:

The Mohawk 5-B was sold specifically as an 11 meter CB amplifier.  This usage is illegal, therefore they attempted to get around the law by claiming it is an amateur radio, 10 meter only amplifier.  Such amplifiers are also illegal to sell, but not to own or operate, as long as such operation is consistent with your licence class.  Of course, no amplifiers are permitted on 11 meters, therefore it is illegal to operate the amplifier on that frequency.

The amplifier employs a single sweep tube, driving a pair of 572B triodes.  If the power supplies are robust enough, you could achieve perhaps 600 watts out of it, for roughly 3 to 5 watts input.  It may have a "high drive" switch which bypasses the sweep tube, then you could drive the two 572Bs with about 30 to 50 watts, and achieve 600 watts cleanly.  This assumes that the power supply delivers a solid 2.2 to 2.4kV and does not sag badly under load.  That's a big assumption for an amplifier intended for CB.

If the amplifier does not have tuning controls, then the input and output networks are too broad, and it will generate splatter and you should consider redesigning the networks.

It would appear that the Maycom company (www.maycomcomm.com) may be able to supply a schematic.
