This is a factory-built 17 meter transceiver.  It has the TCXO installed when built.
In the very nice factory case.  
I tested it but have not had it on the air, so it is like new.
An incredible rig in a small package.  
I tested it for output with various DC input voltages, and it outperformed the specs.  Here is what I found:
