Looking for an ASR Emitter

As the title states, I’m looking for a gently used ASR Emitter I or II, but prefer the I as cost is a big concern and my speakers (Zu Druid V) are very efficient.  

I am am not new to audiogon, though my username is since I forgot my original username and had to start a new profile. I’m also on audio circle as Phishphan. 

Aslo appreciate any feedback or recommendations on similar sounding amps. 

Cheers, 
William
