Opto-isolating my Alpha PA76P

I aquired this amp a few days ago. I'll be driving it with an Icom 7300, then through the TGXL. What I need to know is, can I use the TGXL as an isolation relay? Thet keying voltage on the 7300 is 16VDC 0.5 Amp max, the Alpha is 26VDC @ 74mA max.
I will be connecting the the send from the Icom to the PTT input "B" on the tuner and the PTT output "B" to the Alpha relay in. Looks to my like it should work. but I don't want mess anything up. I have an outboard relay coming, in case I need it. It's a few days away, and I'm getting itchy to fire up this old amp
