Hello,
Is it ok to have a "Y" connector at my ICOM 756 PRO II's RELAY output and have one connection going to the AL-1200 HF amp and the other connection going to a 6 meter amp's relay imput?

As long as the amp NOT in use is off, is there any danger of damage?

OR..what is the easiest way to facilitate operating two amps with one HF rig?

I was planning on using the second antenna jack on the PRO II to operate 6 meters.

Thanks in Advance,

Jose - N4BAA and YI9BAA

I'd use simple diode isolation for this.  It takes two diodes (like 1N4001s) that cost less than ten cents each to do so.

Wire a diode in series with the "center pin" (keyed line) of each amp's relay input line, with the anode to the amp's pin and the cathode to the rig's "amp key" terminal.  So, you'll have two diode cathodes joining in common at the "rig" end of this dual-amp key line.

The grounds can all be common.
