Hello Nitroturbo4U: Ten-4 that sounds like its working ok to me.
Those amps never had a good SSB Keying circuit, coming out of the gates. I used a Contex 500 when I was a kid, it was deal ol Dads amp. I added a 1/4" stereo jack in the back that was wired to the relay, when the radio was keyed on SSB it also keyed the amp, allowing SSB to work quit well. Some add a foot switch but I never liked the foot switch idea.
Also be advised of the high voltage can be a deadly safety issue. Two tubes driving 5 tubes with certainly put the fire in the wire, cheap antennas have been know to catch fire. This is a fine old amplifier. But now the price of replacement tubes may over run its use.
I have a old Palmar Skipper 300 "Chrome Dome Amp" that I am putting a pair of 4CX250B's in and the tubes should be hummin and ah buzzin at full tilt long after I have checked out, at a cost of 135 dollars new each, or a lot cheaper from the ham swap meets.
Good luck
