NB: This choice, and all the following ones are based on direct personal experience. By this I mean I have owned or borrowed similar units to use with my various LFD Audio Amplifiers. The above recommendation worked well for me and assuming the seller is being truthful about the condition, then on the face of it I cannot envisage why it wouldn’t work for you.
That said – as always - buyer beware.
I am not the owner and I'm not the seller. I have no connection with the seller whatsoever.
