Palomar elite 450 HD keying circuit problem

[Drradio61]

Hello all,
I have a Palomar elite 450 HD with four SD 1446s it has a burnt resistor that can't be identified except for the silk screen on the board that says r19. Does anyone have one of these amplifiers or a schematic that could give me an idea of what the value is of that resistor?

Without digging into my amp notes I would say its a 33 ohm 1/2 or 1 watt carbon film resistor. Likely had to much drive into the amp. Also replace that diode by it, likely a 1N4007 will do just fine, this is likely bad too. Anyone correct me as I am just going from memory.
