While the version could very well be the problem, I would look at the keying
voltage and current to be sure it's within the Orion's specifications. IIRC
without looking at the schematic, it uses a 2N3904 to pull down amp keying,
which limits the dissipation. I have had no trouble keying my older TT
Titan (425), and although the voltage is higher than spec, I measured the
current at only 4 ma.
