[ICOM] 756PROIII intermittent output

[Phil Krichbaum]

Larry,
    I'm using it with an Alpha 91B and at the most need about 25-50w to 
drive it and  do it without using the rig's tuner. I replaced it with a 
FT1000MP and the amp works fine with it thru the same coax etc.
    One guy said he had a similar problem with a 746PRO and the thermal 
sensor on fan didn't work so I'll check and see if the fan is coming on. 
I should also try another PS. Thanks!
    Phil

I agree it sounds like it could be a thermal fold back issue, but it could be in one of several places, PA, Ant tuner, or even power supply. Larry K4LXV
