[amsat-bb] pre amp help..

I just sent my ARR pre amp back to ARR for repair for the 3rd time !

(pretty sure I did not tx through it )

What are people using for pre amps. I only see the Mirage as an alternative. Any other choices. I'm kind of disappointed in ARR products. Is there a pre amp that you can tx through preventing accidental frying?

Any thoughts appreciated
